This week's mystery is difficult.......making it a good game to play at a New Year's Eve party.
I was born in Philadelphia (PA) in 1849.
I was known as the Harvard "Math Wizard" because I earned the first Harvard PhD in mathematics in 1873.
The picture on the right, me as a distinguished professor, was being sold on ebay for $75 in September of 2006.
I was an Assistant Professor of Mathematics at Cornell University from 1873 to 1876, and then employed in the same capacity at Harvard in 1876-81, and appointed full professor there in 1881.
I published Elements of Differential Calculus (1879)[sold on e-bay in September for about $6], Elements of Integral Calculus (1881), and the syllabi of the Harvard courses in plane trigonometry, analytical geometry, equations, and methods in analytic geometry.
******* Hall on Harvard's campus is named in my honor.
William Elwood Byerly [1849-1935]
