19290 Schroeder           Discovered 1996 May 15 by JPL/GEODSS NEAT at Haleakala.
Jeff Schroeder (b. 1954) has contributed to the mechanical design and fabrication of all the NEAT cameras, starting with the 1995 NEAT/GEODSS camera, continuing with the 2000 NEAT/MSSS camera and concluding with the 2001 NEAT/Oschin camera. He has worked at the Jet Propulsion Laboratory at JPL for 22 years.
