Washington Irving Stringham was a "Professor of Mathematics and Sometime Dean in the University of California" born in Yorkshire, New York. Stringham is perhaps most notable as the first person to denote the natural logarithm as where is its argument. The use of in place of is commonplace in digital calculators today. "In place of we shall henceforth use the shorter symbol, made up of the initial letters of logarithm and of natural or Napierian." Stringham graduated from Harvard College in 1877. He earned his PhD from Johns Hopkins University in 1880. His dissertation was titled Regular Figures in N-dimensional Space under his advisor James Joseph Sylvester. In 1881 he was in Schwartzbach, Saxony, when he submitted an article on finite groups found in the quaternion algebra. Stringham began his professorship in mathematics at Berkeley in 1882. In 1893 in Chicago, his paper Formulary for an Introduction to Elliptic Functions was read at the International Mathematical Congress held in connection with the World's Columbian Exposition.
