| *Milton Blake Sleeper was not merely the graphic artist. M. B. Sleeper was a noted author and radio designer of his own merit. He designed the Pilot Wasp receiver, collaborated with R. S. Kruse, authored numerous radio books, including, Design Data for Radio Transmitters and Receivers, Radio Phone and Telegraph Receivers for Beginners, Radio Hook-Ups, How To Make Commercial Type Radio Apparatus, and Construction of New Type Transatlantic Receiving Sets all in the 1920s. He was also radio editor of Everyday Engineering and originated the plan for what became the successful 1921 transatlantic test conducted by Paul Godley. Sleeper continued to design radios right into the 1950s. | |
