Here’s an interesting and lovely little classic: A. Ritter v. Miller-Hauenfels Der mühelose Segelflug der Vögel und die segelnde Luftschiffahrt als Endziel hundertjährigen Strebens. (Roughly “The effortless gliding of birds and the sailing airships as the ultimate goal for the end of the century”).The matieral was delivered (January 18th) 1890 at the Polytechnischen Club in Graz and publisahed later that yer in Vienna by Spielhagen & Schurich. My copy of this work also happens to have been in the collection of Vicktor Silberer, 1846-1924, a pioneer aviator from Vienna and a prolific author, jorunalist, and politician.
In his lectures at Graz Miller-Hauenfels looks at the possibility of human (non-powered, gliding) flight via forward-progression bird flight, basing his work on that of Marey, Lilienthal and Parseval.
