to which was added teaching, first as instructor and later as professor of mathematics and natural history. In 1869 Professor Calvin was made principal of the Fourth Ward School of Dubuque where he remained until 1874 when he was elected Professor of Natural Science at the State University, succeeding Dr. C. A. White. At that time the professor of natural science was required to teach geology, zoölogy, physiology and botany. This wide field has been gradually divided among other professors and instructors until Professor Calvin occupied the chair of geology alone. He has been a constant investigator and contributor to the literature of his chosen specialty. He was one of the founders and remains one of the editors of the American Geologist, the oldest exclusively geological journal in America. He was one of the original fellows of the Geological Society of America and has long been a member of the American Association for the Advancement of Science. In 1890 he served as secretary of the geological section and in 1894 as vice-president of the association and presiding officer of the section. His address delivered in Brooklyn, attracted much favorable comment, both in this country and Europe. The degree of M. A. was conferred upon him by Cornell College and that of Ph. D. by Lenox College. In 1892 Professor Calvin was appointed State Geologist of Iowa, which position he has filled with marked ability as shown by the high standing the survey has attained at home and abroad.
“The economical results of the work are becoming more and more apparent and to Professor Calvin the State is mainly indebted for them. He will probably, however, be longest remembered and best known as the teacher of hundreds of men and women occupying important positions throughout the State.”
EDWARD CAMPBELL, farmer, lawmaker and politician, was born in Washington County, Pennsylvania, January 1, 1820. From early boyhood he was obliged to rely upon his own resources but he procured a good education by reading without instruction. He was a Democrat from the time he was old enough to take an interest in politics and during his entire life retained that faith and was one of the trusted leaders of his party in Iowa. He was a warm supporter of Stephen A. Douglas in 1860, and served as sheriff and prothonotary for many years in Pennsylvania before coming to Iowa in 1865. Locating on a farm in Jefferson County, near Fairfield, he became a progressive farmer, intelligent and successful. For ten years he was chairman of the Democratic State Central Committee and one of the most trusted councilors of his party up to the time of William J. Bryan's nomination for President, when he affiliated with the “Gold Standard” wing which supported Palmer for President. He was elected to the House of the Fourteenth General Assembly in the fall of 1871, serving in the regular and extra session, which revised the code.
