Mellen Woodman Haskell
Mellen Woodman Haskell (March 17, 1863 – January 15, 1948) was an American mathematician, specializing in geometry, group theory, and applications of group theory to geometry.

Education and career
After secondary education at Roxbury Latin School, he received in 1883 his bachelor's degree and in 1885 his M.A. and a Parker Traveling Fellowship from Harvard University. From 1885 to 1889 he studied mathematics at the University of Leipzig and the University of Göttingen, where in 1889 he received, under Felix Klein, his Ph.D. (Promotierung).<ref>{{cite book|url=https://books.google.com/books?id=uMvcfEYr6tsC&pg=PA209|author=Parshall, Karen|authorlink=Karen Parshall|author2=Rowe, David E.|authorlink2=David E.

At the University of California, Berkeley, he became in 1890 an assistant professor, in 1894 an associate professor, and in 1906 a full professor. In 1909 he became the chair of U. C. Berkeley's mathematics department in succession to Irving Stringham, and remained the chair until retiring as professor emeritus in 1933.

Haskell was an Invited Speaker of the International Congress of Mathematicians in 1924 in Toronto and in 1928 in Bologna.
