Lewis Frederick Manly (April 23, 1903 – November 2, 1970) was an American athlete, sports coach and professor.

From Erie, Pennsylvania, Manly attended the College of Wooster in Ohio, where he tried out for the football team as a freshman, despite having had no prior experience in interscholastic sports.

He made the team as a sophomore and became one of their top players, helping them go undefeated in his junior year and being an All-Ohio selection as a senior.

In 16 years as head football coach, he compiled a record of 60–48–12, including an undefeated 8–0 season in 1934, with his 60 wins making him the program's all-time leader.

Lewis Frederick Manly was born on April 23, 1903, in Erie, Pennsylvania, to William Jared and Harriet (Miller) Manley.

[3] "[At] a small college like that, equipment isn't any too plentiful so I went out to practice in an old pair of pants, a sweater, and some football shoes I managed to borrow.

"[3] Despite his inexperience, Manly went on to become "one of the star linemen of his time" and in Wooster history, later being inducted into their athletic hall of fame in 2005.

[3][5] Standing at 5 ft 11 in tall, and weighing 185 pounds, Manly was switched to tackle as a junior and helped the team compile an undefeated 9–0 record, winning the OAC championship.

[3][6] The Kentucky Post and Times-Star named Manly and five others as the key players who led Wooster to the undefeated season.

[3][8] He was a 1924 All-Ohio selection and was described by a staff writer at The Akron Beacon Journal as "a thoroughly dependable lineman" and "one of the strongest defensive players on his team.

[13] Manly participated in the shot put events for the Wooster track and field team and at the time of his graduation, had received nine total varsity letters, the all-time record at the school.

[19] The Boston Globe wrote that, "The task was one to cause anyone worry, yet Lew went right ahead, worked hard with the boys every afternoon, taught them the tricks of the lineman's trade, and produced one of the best, if the lightest, lines that ever represented the brown and blue.

[21] He had the largest squad in school history in 1943, and the Jumbos went 6–2; previously, due to lack of men, Manly would have to teach players three to four positions.

"[3] His practices often included games of touch football, kicking contests, and foot races, but did not have tackling dummies or other equipment, with Manly focusing on training and conditioning methods.

[3] The Lewis F. Manly Memorial Prize was named in his honor, given to the Tufts undergraduate who "combines a record of academic excellence with superior athletic performance.
