Haworth, Erasmus, professor of geology and mineralogy, state geologist, and director of the department of mines at the University of Kansas, was born on a farm near Indianola, Warren county, Iowa. In 1883 he received the B. S. degree and the following year the degree of A. M. from the University of Kansas. In 1888 the degree of Ph. D. was conferred on him by the Johns Hopkins University. In 1892 he was appointed professor of geology and mineralogy at the University of Kansas, a position which he still holds. In 1894 he organized the Kansas state geological survey. The reports of the survey are valuable contributions to science. He wrote volumes one, two, three and eight, and part of volume five from 1896 to 1904. He has also written bulletins in connection with the United States geological survey and the Missouri geological survey as well as annual bulletins of statistics of the mineralogy and geology of Kansas. Prof. Haworth has given much attention to economic geology of Kansas and adjoining states in respect to gas, oil, water, coal and cement. An example of his service to the state was in directing the town of Newton how to obtain an ample supply of superior water for domestic use. He has been connected for years with the United States geological survey and has done much professional work for the Union Pacific Railroad company in Wyoming and Kansas and for private parties in Kansas and adjacent states. He is a fellow of the Geological Society of America and other scientific societies. In 1889 he married Miss Ida E. Hunstman of Oskaloosa, Iowa.
