246238 Crampton           Discovered 2007 Sept. 5 by D. D. Balam at Mauna Kea.
David Crampton (b. 1942) has overseen the development of exceptionally efficient, multiplexed spectrographs for CFHT and Gemini. Using them he helped establish Canadian excellence in observational cosmology. He has also excelled in research on Galactic structure and multiple stars, including X-ray binaries.
