Alexander Leydenfrost (Baron Sándor Leidenfrost) (March 18, 1888 in Debrecen – June 1961) was a Hungarian-born American industrial designer and illustrator.
[2] Upon moving to the United States in the 1920s Leydenfrost altered the spelling of his name in an attempt to correct the mispronunciation of his name, and also changed his name from Sándor to the equivalent "Alexander".
The collapse of Austria-Hungary caused him to emigrate to the United States in 1923, where he began working for the well known artist-illustrator William Andrew Pogany, designing stage sets and painting large murals, as well as being a featured regular in magazine publications.
He continued to illustrate for Life throughout his career, in addition to other major magazines including Skyways, Liberty, Look, Popular Science and Esquire.
[6] Despite the small body of work he created for Planet Stories,[7] many science fiction enthusiasts consider his artwork for that magazine to be that publication's finest.
