52294 Detlef           Discovered 1990 Oct. 12 by L.D.Schmadel and F. Börngen at Tautenburg.
Detlef Ninnemann (b. 1944) is a German patent attorney and electrical engineer, who trained a generation of trainee patent attorneys in the rigorous application of logic, science and language in their work. He also taught by example to deliver complex arguments in a direct way. Name proposed by the first discoverer.
