HAROLD 0. MARSH 
Harold Oscar Marsh died September 10, 1918, at Chester, N. J., 
the place of his birth. 
Mr. Marsh was born November 6, 1885. He was educated in the 
public schools at Chester and took a special course in entomology at the 
Kansas Agricultural College, Manhattan, Kansas, in 1914. Prior to 
his employment in the Federal Bureau of Entomology, he was engaged 
in special work under the direction of the State Entomologist of New 
Jersey, and later of the State Zoologist of Pennsylvania at Harrisburg. 
He was first appointed in the Bureau of Entomology July 1, 1908, hav¬ 
ing served ten years as an entomological assistant in truck-crop insect 
investigations. In the Civil Service examination which he took in 
economic entomology he obtained the highest rating among quite a 
number of applicants. His first employment was in Washington, 
D. C.; later he was in charge of sugar-beet insect investigations at 
Rocky Ford, Colorado, and at times was also engaged in similar work 
on truck-crop pests at Brownsville, Texas, in California, and for a 
short time in Hawaii. His principal work was accomplished while in 
Colorado. He had recently retired from active work in the Bureau, in 
order to take charge of his farm in New Jersey, where he was em¬ 
ployed as a collaborator, but he had planned to resume active work in 
the early spring. 
Mr. Marsh was an enthusiast, an observer of unusual excellence 
and was particularly adept at life-history work, excelling especially in 
obtaining the various stages of an insect and determining the life cycle 
and generations. He was unusually skillful in mounting and preparing 
all specimens which came under his notice, and this attracted much 
favorable comment. He was also a careful experimenter and kept 
accurate records of all his work. 
Personally, Mr. Marsh was well liked in the community where he 
worked and by others who knew him; he was always prompt, painstak¬ 
ing and earnest, working early and late whenever the occasion de¬ 
manded. In spite of a heavy handicap, a frail physique and eye 
troubles, he succeeded in accomplishing a great deal of work. The 
following is a list of his principal publications: 
Biologic and Economic Notes on the Yellow-Bear Caterpillar. Bui. 82, pt. V, Bur. 
Ent., U. S. Dept. Agr., Aug. 31, 1910.
