Horace Greely Prettyman (November 8, 1857[1] – March 27, 1945) was an American football player in the early years of the sport.

He was the team's captain in 1884, 1885, and 1886, and scored the first touchdown in the first game played at Michigan's first home football field in Ann Arbor.

Prettyman attended Ann Arbor High School and subsequently enrolled in the University of Michigan in 1882 at age 24 and excelled as an athlete.

[5] The team played its first ever home game[6] at the Ann Arbor Fairgrounds in March 1883, a 40-5 win over the Detroit Independents.

The trip consisted of four road games in eight days at Wesleyan and Yale in Connecticut, Harvard in Massachusetts, and Stevens Institute in Hoboken, New Jersey.

"[10]Late in the game, Michigan appeared to have scored the winning touchdown on a trick play, called "the time-honored fake run.

"[11] Prettyman began running with teammate (and future Boston Red Sox owner) Henry Killilea behind him.

"[11] After the final game of the Eastern trip against Stevens Institute, The New York Times noted that Killilea and Prettyman "did some of the best work for the Michigan men in the way of running and tackling.

The team won both of its intercollegiate games, including an 18 to 10 win in its first match against its eventual rival, the University of Chicago.

Michigan won the football game 24 to 0,[16] and the Argonaut reported that "Prettyman's play was characterized by his usual heavy rushing.

[1] Though he was no longer a student, college football eligibility standards were loose, and Prettyman returned to play three more years for Michigan, as the team's center in 1888,[21] and as a tackle in 1889 and 1890.

This came near bringing on a fight and the crowd broke into the field and surrounded the players closely while the occupants of the grand stand hissed the unexpected display.

"[25]In 1890, Prettyman played as part of the first racially integrated football team at Michigan, alongside African-American teammate George Jewett.
