Washington Irving Stringham (December 10, 1847 – October 5, 1909) was an American mathematician born in Yorkshire, New York. He was the first person to denote the natural logarithm as $\ln(x)$ where $x$ is its argument. The use of $\ln(x)$ in place of $\log _{e}(x)$ is commonplace in digital calculators today.

"In place of $^{e}\log$ we shall henceforth use the shorter symbol $\ln$ , made up of the initial letters of logarithm and of natural or Napierian."[1]

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[2] 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.[3]

Stringham began his professorship in mathematics at Berkeley in 1882.[4] 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.[5] In 1900 he was an Invited Speaker at the ICM in Paris.[6]

Personal life

Irving married Martha Sherman Day. The couple raised a daughter, Martha Sherman Stringham, (March 5, 1891- August 7, 1967).

gollark: Although I think it can still get caught up in uselessness and signalling quite easily.

gollark: Yes, that is somewhat better.

gollark: "Debate" mostly isn't actual meaningful debate but just showing how virtuous you are for showing how terrible the Other Side is.

gollark: It's much more about tribal signalling than actual policy and doing useful things.

gollark: You can't actually do anything significant to them in most cases, and they monopolize vast amounts of people's attention and communication bandwidth.
