First appearance of a diagram of a “wormhole”--the coining of the term would come later in 1957 by Whweeler and Meissner. (The word appears for the first time in English in Shakespeare Lucrece “To fill with worme-holes stately monuments” in 1594—this is not what Wheeler had in mind.) The “geon” (“gravitational electromagnetic entity”) is the word used for “wormhole” here, building on the “bridige” (Einstein-Rosen bridge that I think is mentioned in the last Avenger's universe movie!) idea built by Einstein and Nathan Rosen in 1935 as a means to connect two different points in space-time, and also on the work of Hermann Weyl (“Feld u. Materie” in AdP 65(14) 541-563 1921,) and the still-earlier work in the Phys Zeit 1916 by Ludwig Flamm who theorized on this idea in terms of what we would call a “white hole”.
[Wormhole: “...is a speculative structure linking disparate points in spacetime, and is based on a special solution of the Einstein field equations solved using a Jacobian matrix and determinant. A wormhole can be visualized as a tunnel with two ends, each at separate points in spacetime (i.e., different locations or different points of time). More precisely it is a transcendental bijection of the spacetime continuum, an asymptotic projection of the Calabi–Yau manifold manifesting itself in Anti-de Sitter space. --Wikipedia]
