William Seymour Tyler (September 2, 1810 – November 19, 1897) was the Amherst College, Massachusetts, historian during his tenure as professor of Latin, Greek, and Greek literature from 1832 to 1893.

He was born September 2, 1810, in Harford, Pennsylvania,[1] the son of Joab and Nabby née Seymour Tyler.

He edited many Greek and Latin texts, and was the author of History of Amherst College During Its First Half Century (1872) and History of Amherst College during the Administration of its First Five Presidents (1894).

In the latter he claimed that Amherst was the first U.S. college to use Latin honors, although it appears that Harvard deserves that distinction.

[2] Tyler House, a dormitory building at Amherst College, was also named in his honor.
