10509 Heinrichkayser           Discovered 1989 Apr. 3 by E. W. Elst at the European Southern Observatory.
Heinrich Gustav Johannes Kayser (1853-1940) was a German physicist who demonstrated the presence of helium in the earth's atmosphere. Using the spectra of a large number of elements, he discovered closely grouped spectral lines, the spacing and intensity of which vary in a regular manner.
