Henry Cummings "Tillie" Lamar (October 4, 1865 – March 10, 1891) was a college football player.

The season was notable for one of the most celebrated football plays of the 19th century - a 90-yard punt return by Lamar of Princeton in the closing minutes of the game against Yale.

[3] Lamar streaked down the left sideline, until hemmed in by two Princeton players, then cut sharply to the middle of the field, ducking under their arms and breaking loose for the touchdown.

For the first time, the game was played on one of the campuses instead of at a neutral site, and emerged as a major social event, attracting ladies to its audience as well as students and male spectators.

[6][7] Lamar, the grandson of Henry Cumming who conceived of and promoted the construction of the Augusta Canal, died by drowning at the opening of the canal connecting Lake Olmstead with the Savannah River, near Augusta, Georgia.
