    “The first IRT subway ran between City Hall and 145th Street at Broadway, opening on October 27, 1904. It opened following more than twenty years of public debate on the merits of subways versus the existing elevated rail system and on various proposed routes.

    Founded on May 6, 1902, by August Belmont, Jr., the IRT’s mission was to operate New York City’s initial underground rapid transit system after Belmont’s and John B. McDonald’s Rapid Transit Construction Company was awarded the rights to build the railway line in 1900, outbidding Andrew Onderdonk. On April 1, 1903, over a year before its first subway line opened, the IRT acquired the pre-existing elevated Manhattan Railway by lease, gaining a monopoly on rapid transit in Manhattan. The Manhattan EL was the operator of four elevated railways in Manhattan with an extension into the Bronx. The IRT coordinated some services between what became its subway and elevated divisions, but all the lines of the former Manhattan EL have since been dismantled. In 1913, as a result of massive expansion in the city, the IRT signed the Dual Contracts with Brooklyn Rapid Transit (BRT) in order to expand the subway.  The agreement also locked the subway fare at 5 cents for forty-nine years. The IRT unsuccessfully attempted to raise the fare to seven cents in 1929, in a case that went to the United States Supreme Court.”–Wikipedia (on the IRT)

  • A Moving Sidewalk, NYC, 1903

    Transportation of passengers in Greater New York by continuous railway train, or moving platforms. Argument in favor of equipping the East River bridges, and connecting subway to Bowling-Green, Manhattan, with moving platforms, prepared for Schmidt & Gallatin. New York, 1903. (No indication of publisher.)

    9″x 6”, 20pp, plus 4 folding plates (including a map).

    Original wrappers. Condition: the original wrappers are chipped and detached. The text however is clean and bright. Overall, this is probably a GOOD copy (only), probably a 5 out of 10 (“10” being “new”).  Only six copies located in WorldCat (Henry Ford, Yale, U Chicago, NYHS, NYPL, Columbia). 

    Provenance: US Customs House (NYC, Herman Melville retiring from there in 1885 btw) with their tiny rubber stamp barely visible on the front wrapper; Library of Congress (with their rubber stamp on rear cover, which probably resulted in the wrappers detaching).  $250

      Continuous railway

     

    DocFile (2)

    This seems a wonderful example of future thinking and city planning–but just not a very good idea.  It is hard to imagine a continuously moving sidewalk functioning in lower Manhattan. 

    Continuous railway _2_

    From the pamphlet: 

    “Moving Platforms for the conveyance of passengers were recommended by Mr. Horace Greeley thirty years ago. They were successfully operated, first, at the World’s Columbian Exposition of 1893, where 2,700,000 people were transported. In 1896 they were installed at the Berlin Exposition, and again at the Paris Exposition of 1900, where they carried over eight million passengers. Few persons know what Moving Platforms are. From the face that sometimes they are called ” Moving Side- walks,” it is believed that they must be some sort of a pavement on rollers, on which it is difficult to step with safety and maintain equilibrium. The Moving Platforms are to all intents a railway, operated like other railways, propelled by electricity, with cars, seats, motors, passenger stations, ticket booths, guards, electric lights — in fact, everything belonging to a first-class railway.” 

    “Where it differs from the ordinary railway is that the cars, or trains, are not running at intervals, but are coupled up continuously, so that there is no interruption of traffic at any time, but a large seating capacity at all times. It differs also in the construction of the cars, which are mere flat cars, provided with seats placed crosswise, and so arranged that all passengers face in the direction of motion. Each of these seats may be made wide enough to accommodate one, two or more persons. The most approved plan is to provide seats on one side of the cars only and leave the other for passengers to walk, thus giving them an opportunity to further accelerate their speed if they so desire…”

  • Four Cosmology Papers by R.C. Tolman, 1931-2

    Richard C. Tolman, “On the theoretical Requirements for a Periodic Behaviour of the Universe”, in Physical Review, vol 38/9, November 1, 1931,  pp 1758-1771 in the issue of pp 1575-1796.

    And offered with:

    • Tolman RC. “Nonstatic model of universe with reversible annihilation of matter.” Physical Review. 38/4, August 15, 1931. 797-814. VG+ copy
    • Tolman RC. “Possibilities in relativistic thermodynamics for irreversible processes without exhaustion of free energy.” Physical Review, vol 39/2, January 15, 1932, pp 320-336. About a 1/4-inch chip missing from top of spine. [Also contains M. True et. al., “High Speed Protons”.] VG copy
    • Tolman RC, Ehrenfest P, Podolsky B. “On the gravitational field produced by light.” Physical Review, vol 37/5, March 1, 1931, pp 602-615. VG copy.

    All in original wrappers.

    All copies are 3-hole three-ring-bound, meaning that the decrepit binding was removed to reveal  nicely preserved issues, with lovely spines (which on the Phys Rev are easily damaged), but with the three binding holes through-and-through. So, there’s that. 4 issues: $200

    Tolman was a Ph.D. MIT (1910), then positions at University Michigan (1910-11), (1912-1916), then U Cincinnati and U of Illinois before US WWI involvement, then on to  UC Berkeley, and then  CalTech (1922-1948). During World War II, “Tolman served as vice chairman of the National Defense Research Committee, as scientific adviser to General Leslie R. Groves on the Manhattan Project.”–DSB
    The main thrust of Tolman’s work in statistical mechanics, relativistic thermodynamics, and cosmology was mathematical and theoretical.  An “…early interest in relativity theory was further stimulated by Hubble’s discovery in 1929 that red shifts are proportional to distance, and led to a series of studies on the applications of the general theory to the overall structure and evolution of the universe. In his comprehensive treatise on relativistic thermodynamics, Tolman presented his theory of a universe expanding and contracting rhythmically like a beating heart, arguing that gravity has the effect of counteracting the influence of radiation, thus preventing the complete cessation of motion as predicted by the second law of thermodynamics.”–DSB

    Abstract from the first paper, “On the theoretical Requirements for a Periodic Behaviour of the Universe”: “This article investigates, on the basis of relativistic mechanics and relativistic thermodynamics, the theoretical requirements for nonstatic models of the universe to exhibit a behaviour which is periodic in time. The discussion is limited to models which can be regarded from a large-scale point of view as filled with a uniform distribution of fluid, and the time coordinate is purposely chosen so as to agree with the proper time that would be used by local observers at rest in this fluid. It is first shown that the analytical requirements which would correspond to the continuous expansion and contraction of such models between definite maximum and minimum limits, together with the thermodynamic requirement that the expansion and contraction must be reversible, could not both be simultaneously satisfied with any fluid for filling the model which has reasonable properties. Attention is then turned to models of the universe having line elements which would be quasi-periodic in the time. A wide range of possibilities is found for models which would expand from zero proper volume to a maximum and then return, the treatment failing however to provide the analytical conditions for a minimum at the lower limit. It is pointed out, nevertheless, that from a physical point of view contraction to zero proper volume could only be followed by renewed expansion, so that we might expect for such models a continued series of expansions and contractions. Furthermore, it is found possible to satisfy the analytical requirements for such quasi-periodic behaviour by models which would expand and contract at a finite rate reversibly without increase in entropy, so that we might then expect a continued series of identical expansions and contractions. It is pointed out that Einstein’s recent model of a nonstatic universe filled with incoherent matter, exerting no pressure and unaccompanied by radiation, would satisfy the thermodynamic as well as the analytical requirements for such a series of identical repetitions, and models filled solely with black-body radiation and with an equilibrium mixture of radiation and perfect gas are discussed which also satisfy these requirements. In conclusion some remarks are made concerning the bearing of such findings on the behaviour of the actual universe. “

  • Financial Report on Engineering in the Orleans Levee District, 1935

    Welsh & Green, Inc (Chicago).   Orleans Levee District, Orleans Parish, Louisiana.   No publisher, no place of printing, April 1935.  11.5×8″, 31 leaves, plus (20) leaves, including 5 folding plates of tables and one map.  This is a offset type-printed document, presumably done so in very small numbers, for a presentation made by the firm of Welsh & Green before the Orleans Levee District Board, recommending ways of financing the various improvements to the levees and the airport. 

    This report is bound in a stiff manila folder with brass punches and has a hand-made typed label pasted onto the front cover.  The cover has some bumps and tears along the edges but is in generally Very Good condition; the text is Fine. Provenance: the Library of Congress, with their surplus/duplicate stamp on the rear page. $300

    Levee Report

    “Welsh & Green was retained by Newman, Harris & Co., of New Orleans, to investigate the financial conditions of the district, and to devise ways and means for remedying the (financial) situation.” In effect it seems as though this presentation looked at different ways to legislate and issue bonds to fund a 7 million dollar public debt for the work.

    The report was issued in April 1935, just a few months ahead of the “other” storm of the century, the Labor Day Storm of 1935. NOT LOCATED in the OCLC/WorldCat. I can’t locate this anywhere, so far, except for the Catalog of Copyright Entries for 1935. (I did find something that looked similar to this report by Welsh & Green on the financial status of Chicago, 1934.)

  • A Strong Statement Made in Defense of the Environment, 1921

    Preservation of Natural Conditions 9×6″, 32pp, illustrations. Original wrappers. 

    OFFERED WITH:

    Preserves of Natural Conditions, both published by the Ecological Society of America (Committee on the Preservation of Natural Conditions), reprinted 1921 with assistance of NRC. 9×6″, 31pp. Originl wrappers. This copy also accompanied by a 2pp guideline (dated November 1921) for readers who cared to participate in recommending areas in their vicinity for preservation.  

    These two pamphlets seem to be one in the same work, though there are a number of significant differences among the many similarities. Both copies in Very Good condition, with Library of Congress surplus/duplicate rubber stamps on the back cover. $125/the pair

    DocFile (7)

    The pamphlets make the case for scientific selection of preserves to take place in the U.S. before it was too late to save those areas from abuse and exploitation. Of the many cases made for this activity:

    • “The automobile is fast opening up the most inaccessible sections of the country to the hunter and the industrial exploiter as well as to every week end excursionist who chances to own a tin Lizzie. All are combining to destroy our native fauna and flora and to upset the general balance which was maintained for ages before the entrance of man. Nearly every day’s papers throughout the summer and fall chronicle a considerable list of forest fires most of which according to wardens are due to carelessness on the part of campers or hunters. But this list does not include the hundreds of square miles of brush and chaparral which are burned over every season.” Francis Bertody Sumner, 1874-1945 (Scripps Institution for Scientific Research, La Jolla), one of the first biologists at Scripps.
    • “Any statesman like view of the situation will convince one that the people who live in this country fifty years hence will be extremely grateful to this generation for every area it may succeed in having reserved however the present need of preservation may appear.” G. Biggs

    All of these guys were pretty much right on pretty much everything. 

    Two notes on the ESA:

    • “Between 1917 and 1945, the Ecological Society of America (ESA) housed a Committee for the Preservation of Natural Conditions specifically charged with identifying and taking political action toward the preservation of wilderness sites for scientific study.”  Journal of the History of Biology, Nov 2012, Volume 45, Issue 4, pp 613–650|
    • “In 1917 the Ecological Society of America established a committee for the Preservation of Natural Conditions for Ecological Study, under the chairmanship of Victor E. Shelford, “to initiate and carry out action concerned with preservation of natural conditions” (Bulletin ESA 1 [4]: 1). Dr. Shelford was one of the founders of the Society in 1914 and had served as its first president. Also, in 1926 The Naturalists’ Guide to the Americas was published under his editorship. This volume made a preliminary inventory of natural areas in the new world, and it served as a guide for pointing out areas in need of preservation.”.

  • Floating Transoceanic Airport Network, 1936–from the White House Library

    DocFile (5)Edward R. Armstrong (1880-1955). Application of Seadrome Ocean Dock Corporation (a private corporation) for a Loan Under the Provisions of the National Industrial Recovery Act, printed ca. 1933.  11×8 inches, 34pp.  With two original photographs one of the floating airports, and a map.  This copy comes from the White House Library, transferred to the Library of Congress in 1933. Printed wrappers. There is a Library of Congress surplus stamp on the rear cover, ans a tiny “LC” perforated stamp at the bottom of page one. Very nice copy.  $500 

    The outline for this plan asks the federal government for a loan of $30 million (Depression) dollars to undertake the construction of a five floating airports transoceanic network.  “It will require the work of approximately 10,000 men per month for a period of twenty-four to thirty months”.  The labor figures did not include was what necessary to produce all of the material necessary for the project ( for reasons unknown).  Once finished the network would enable aircraft  to make it across the ocean in 18 to 36 hours.

    The members of the Seadrome Corporation estimated that the entire 30 million would be paid back by 1945,  and that the corporation would be completely debt-free.  Perhaps all of  this made sense when Armstrong first developed the plan in 1913, just ten years after the Wright brothers’ successful first in North Carolina. The idea of the floating airport girding the Atlantic was a pretty interesting idea, seeing as how the world record for sustained non-stop flight in 1913 was 11 hours (in a Maurice Farman MF-2), and that was under more-or-less optimal conditions; the speed record was 120mph, and again, optimal conditions and not sustained for hours on end.  By 1933 it seems to me that it had become obvious that non-stop transoceanic flight was coming, and coming soon.  That would of course make an investment in the Seadrome project superfluous, like building an antique, though an unnecessary one. The first transatlantic non-stop flight was made by John Alcock and Arthur W. Brown in 1919, averaging about 100mph; Lindbergh would come later to accomplish the first solo non-stop in 1927–by the early 1950’s jet aircraft would be making the trip with regularity, which means that  for most of the life of the completed Seadrome it would have been unnecessary.  I feel certain that the Seadrome–which was supposed to be paid off by 1945, though in 1933 there was no inkling on the part of the Corporation members who wrote the request for the money that a war was looming and that there would have been almost no way for them to have been made at any time between 1939 and 1945–would never have been paid for.Armstrong’s idea would get major play in the popular press from time-to-time, and discussed as a series of floating islands.  Armstrong himself would organize the Seadrome Ocean Dock Corp. in the late 1930’s, his pretty but  impractical idea (reported by Time Magazine1 in 1933 as little more than “a perennial gift to Sunday feature editors”)  finally grinding to a salty end with greater fuel capacity and efficiency in transatlantic aircraft.

  • Ludwik Silberstein Contribution To The Quantum Theory Of Spectrum Emission Spectra Of Atomic Systems Containing A Complex N

    SIlberstein313Ludwik Silberstein.  “Contribution to the Quantum Theory of Spectrum Emission: Spectra of Atomic Systems Containing a Complex Nucleus.”  Offprint:  Philosophical Magazine, vol xxxix, January 1920. 

    Original printed wrappers.pp 46-66.  Inscribed, “with the author’s best regards, 21.I.1920”.  $125

    Silberstein was as we all know an interesting thinker, working early and with some elegance in relativity, though he did run into a spot of bother with Einstein in which the good Dr. Silberstein fared not so well. I’ve always rather “liked” Silberstein for his early work on relativity. 

     “Ludwik Silberstein (1872 – 1948) was a Polish-American physicist who helped make special relativity and general relativity staples of university coursework. His textbook The Theory of Relativity was published by Macmillan in 1914 with a second edition, expanded to include general relativity, in 1924.”–Wikipedia

  • First Appearance in Print of the Terms “Relativity Theory” and “Theory of Relativity” (1906)

    Max Planck, “Die Kaufmannschen Messungen der Ablenkbarkeit der β-Strahlen in ihrer Bedeutung für die Dynamik der Elektronen” [The Measurements of Kaufmann on the Deflectability of β-Rays in their Importance for the Dynamics of the Electrons], in a bound volume of Physikalische Zeitschrift, 1906, volume VII, the paper occupying pp 753-761 (printed in double columns), printed in Leipzig by S. Hirzel. There are other papers of relativity in VII including Wacker (p 300), Farkas (p 654), Stark (p 353), and Wilkens (p. 846). Bound in cloth. Fine and sturdy copy.  $500

    Prior to using the words “postulate” and “principle” associated with relativity (as in “Prinzip der Relativitat”, appearing in the second paragraph of Einstein’s June 1905 “Zur Elektrodynamik bewegter Körper” in Annalen der Physik)  it is first referred to as “relativity theory” (“Relativtheorie”) by Max Planck on p. 756 (col 2 line 9 and also on pp 758+759) of this volume. Then in the “discussion” part of the Planck paper the “theory of relativity” (“Einsteinische Relativitatstheorie”) appears for the first time in print just a few pages later (p. 760 col 2 line 15) by Alfred Bucherer.

    • “The term “theory of relativity” was based on the expression “relative theory” (German: Relativtheorie) used in 1906 by Planck, who emphasized how the theory uses the principle of relativity. In the discussion section of the same paper, Alfred Bucherer used for the first time the expression “theory of relativity” (German: Relativitätstheorie).”–Wikipedia

    It was very surprising, finding this, the first time that something so familiar as “relativity theory” appeared in its most familiar form.
