Robert Lous Olin (July 4, 1908 – December 16, 1956) was an American boxer who became the World Light Heavyweight champion on November 16, 1934, against Maxie Rosenbloom at Madison Square Garden.

After graduating from Erasmus High, he attended Fordham Law School for two years while working as a messenger for a Wall Street brokerage office.

[5][6] Boxing as an amateur, Olin won the New York City Golden Gloves Light Heavyweight 175 lb (79 kg) Open Championship in 1928.

[8] On October 22, 1930, Olin bested Willard Dix in a hard-fought ten round points decision at New York's Madison Square Garden.

It was a dull, close, mauling bout with little boxing or long range blows, and the decision was unpopular with many fans, but Banovic was an accomplished opponent and the win helped pave Olin's path toward a light heavyweight championship attempt[11] On July 27, 1931, Olin defeated Al Gainer, a determined World Light Heavyweight Championship contender, in a ten-round bout at White City Stadium in New Haven, Connecticut.

[12][2] On December 18, 1931, Olin achieved a fourth-round knockout of Tait Littman in the opening round of the National Boxing Association World Light Heavyweight Tournament at Chicago Stadium.

[13] Twelve days later in the tournament's second round on December 30, Olin won over Cylde Chastain in a ten-round split decision.

Though he managed to finish the bout, he was unable to use his right hand for uppercuts or to block as effectively, and Hittick countered with blows to the body in the remaining rounds.

[15] Al Gainer handed Olin a disappointing loss in their third meeting on September 1, 1932, in a ten-round points decision at West Haven, Connecticut.

[17] Olin took a six-round points decision on October 9, 1933, at Madison Square Garden against Black boxer Ed "Unknown" Winston.

[18] On November 17, 1933, Olin just managed to win the decision in a hard-fought eight round bout with Charley Massera at Madison Square Garden.

[19] Olin lost to Lou Brouillard, former National Boxing Association World Welterweight Champion, on January 19, 1934, in a ten-round split decision in New York's Madison Square Garden.

Olin charged to the middle of the ring, and landed a left hook to the chin of Godwin only five seconds into the bout, immediately dropping him for a no count.

Godwin resumed fighting only to face a two fisted assault from Olin against the ropes that sank him to the canvas for the final time for a count of seven.

After fifteen dull rounds, Olin won the decision to an opponent who many ringside believed was totally disinterested in maintaining his title.

[25][3] Boxing as Light Heavyweight Champion, Olin humbled Henry Firpo in a third-round knockout at the Convention Hall in Asbury Park, New Jersey on September 20, 1935.

[2] Firpo was unable to mount a defense against Olin's consistent blows to the body which nearly downed him by the end of the second round, though he was saved by the bell.

[27][28][29] Following his title loss to Lewis, Olin lost to French boxer Al McCoy on December 10, 1935, in a crushing ten round points decision at the Forum in Montreal, Canada.

[30] In one of his better late career matches as a fringe Heavyweight contender on April 2, 1936, Olin lost to Tommy Farr at Royal Albert Hall in Kensington, England in a fifteen-round points decision.

Olin took vicious blows to his head in the two round bout, and received a deep gash under his right eye, later requiring six stitches to close.

[33][1][34] Olin won a decisive victory over Patsy Perroni on September 13, 1937, in a third-round technical knockout at the Convention Hall in Toldedo, Ohio.

[35] On September 28, 1937, Olin lost a sixth-round TKO to Leroy Haynes at Convention Hall in Philadelphia due to a cut eye which was bleeding.
