79410 Wallerius           Discovered 1997 May 3 by E. W. Elst at the European Southern Observatory.
Swedish chemist and mineralogist Johan Gottschalk Wallerius (1709-1785) was the first holder (from 1750) of a professorship in chemistry, medicine and pharmacy at Uppsala University. He is considered the founder of agricultural chemistry. In 1761 he published his main work, Agriculturae fundamenta chemica.
