Deutscher Hausschatz, 53. Jahrgang [53rd Year], 1926/27: Bound.

Deutscher Hausschatz was a general-interest, richly illustrated Catholic family magazine of fiction, poetry, and popular science, unrelated to rocketry apart from one essay: Max Valier’s “Der Vorstoß in den Weltenraum” [The Advance into Outer Space] (pp.119–121), the same title as his full-length book of 1924–25, also in this collection.

Valier names Goddard and Oberth directly, walks readers through the rocket mass-ratio problem via the recoil of a gun mounted on a railway wagon, and sets Goddard’s 2,434 m/sec exhaust velocity with solid propellants against Oberth’s 2,200–4,220 m/sec with alcohol and liquid oxygen, which Oberth hoped to push to 5,000 m/sec.

Five imaginative plates illustrate a spacecraft escaping Earth’s gravity, its cutaway interior, a tethered spacewalk near the Moon, the return home, and a future Earth-Moon spaceport; the essay closes by forecasting intercontinental rocket planes and a Moon landing before the year 2000.

A footnote credits the piece as reprinted, with the publisher’s permission, from Paul Siebertz’s 1927 anthology Wunder im Weltall, issued by the same Munich house.
