John M. Milne (1850-1905) was the second head of the institution that is today the State University of New York at Geneseo.
After John Milne graduated from Brockport in 1871, he studied a year at the University of Rochester.
When the Geneseo State Normal School opened, he was elected teacher of Greek and Latin.
While carrying on his work as a teacher, he continued his studies at Rochester and received a degree in 1879.
He taught at Geneseo until October 1889 when his brother William resigned the principalship, and he was elected to succeed him.
