43790 Ferdinandbraun           Discovered 1990 Oct. 12 by F. Börngen and L. D. Schmadel at Tautenburg.
In 1897, German Ferdinand Braun (1850-1918) introduced a cathode-ray tube with a fluorescent screen ("Braun tube"), the forerunner of the television tube. In 1909, he shared with Marconi the Nobel Prize in physics for the development of wireless telegraphy.
