A BIOGRAPHICAL AND BIBLIOGRAPHICAL SKETCH OF 



OTTO HEIDEMANN. 



By L. O. HOWARD, E. A. SCHWARZ AND A. BUSCK. 



Otto Heidemann was born in Magdeberg, Germany, on September 

 1, 1842. At the age of seventeen he secured a position with the 

 publishing house of F. A. Brockhause at Leipzig, where he learned 

 the art of wood engraving, following this profession for the next 

 three years in various cities in Southern German}^. At the close 

 of the Franco-Prussian war he came to America and estab- 

 lished an engraving office in Baltimore, moving to Washing- 

 ton in 1876. During the next few years he furnished illustra- 

 tions for a number of Government publications. In 1880 he 

 entered the office of Captain G. Wheeler's Geographical Survey 

 as a topographical draftsman. In 1883 he was appointed engraver 

 for the U. S. Department of Agriculture, which position he held 

 for twelve years. During this time he furnished many excellent 

 engravings of economic insects for the Government publications. 

 Through this work he naturally became interested in insects, and 

 during the early nineties under the guidance of his friends Albert 

 Koebele, E. A. Schwarz and Theodore Pergande began the serious 

 study of Entomology. In 1898 he entered the Bureau of Ento- 

 mology as an Entomological assistant and specialist in Hemiptera. 

 From then on his advance was rapid and in a few years he had 

 risen to the position of a recognized authority in this order and 

 has earned the esteem of such specialists as Uhler, Bergroth and 

 Renter. He was appointed Honorary Custodian of Hemiptera 

 in the Insect Division of the U. S. National Museum in 1907 and 

 presided over the Entomological Society of Washington for two 

 terms (1909-1910). At the time of his death he was also a mem- 

 ber of the Biological Society of Washington, of the American 

 Association of Economic Entomologists, a charter member of the 

 Entomological Society of America and a fellow of the American 

 Association for Advancement of Science. 



He is survived by his wife, Mica Heidemann, well known as a 

 sculptress and maker of insect models.
