Ellis was born in 1906 in Norwood, Massachusetts. His family moved to Gloucester and then to Medford, where Ellis attended Medford High School, graduating in 1925. Ellis entered Tufts University that fall, majoring in civil engineering. Ellis lettered in four sports – football, basketball, baseball, and track – at Tufts, from which he graduated in 1929. He was the first Tufts student to earn varsity letters in four sports. In the summers of 1928 and 1929, he played for Orleans in the Cape Cod Baseball League. Ellis is best remembered for his time playing football. He played quarterback for the Tufts football team from 1926 to 1928, scoring a school-record 181 points. That record stood until 2016, when Shayne "Chance" Brady finished his Tufts career with 210 points. Ellis led the 1927 squad to an undefeated season, with the Jumbos posting a perfect 8–0 record. Ellis' future wife, Dorothea Loughlin, attended Jackson College – the women's college associated with Tufts – from 1927 to 1931 and played on the Jackson baseball team.
Later life
For a period of time after graduating, Ellis coached at Dean Academy. His stint included a period of time during which the team assembled three consecutive undefeated seasons. Ellis eventually returned to Medford and served as the head football coach at Tufts from 1946 to 1953, compiling a record of 25–34–6. He was also the head basketball coach from 1946 to 1953, tallying a mark of 74–75. In 1954, Ellis became a full professor and the chairman of Tufts' Department of Physical Education.
Death and honors
Ellis died of a heart attack at the age of 61 on July 19, 1967, at his home in Burlington, Massachusetts. He was survived by Dorothea and their two daughters, Faith and Susan, both of whom graduated from Tufts. Dorothea passed away on October 14, 2011. The football field at Tufts University was named in his honor as Frederick M. Ellis Oval at homecoming in 1969. The Frederick M. Ellis Prize Scholarship at Tufts is named in his memory. On April 21, 2018, Ellis was a member of the inaugural class inducted into the Tufts University Athletics Hall of Fame.
