Washington Irving Stringham (December 10, 1847 – October 5, 1909) 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 ${\displaystyle \ln(x)}$ where ${\displaystyle x}$ is its argument. The use of ${\displaystyle \ln(x)}$ in place of ${\displaystyle \log _{e}(x)}$ is commonplace in digital calculators today.
