Hardy Campbell Sr. was involved in horse racing, and Hardy Jr. spent his life around and in the business. He became head stable lad forDwyer Brothers Stable inBrooklyn, New York, one of the top racing operations in the United States. While working for the Dwyer stable, Hardy Campbell Jr. learned racehorse conditioning from futureHall of Fame trainersJames G. Rowe Sr. andFrank McCabe. The Dwyer brothers racing partnership was dissolved in 1890 andMike Dwyer offered Campbell the job of head trainer for his stable and for the next seven years the two met with considerable success.

During his career, Campbell trained some of the best horses of the 1890s including 1891American Horse of the Year and 1891 and 1892American Champion Older Male Horse,Longstreet, the 1896 and 1897 National Champion fillyCleophus, as well as Hall of Fame inductees,Kingston andBen Brush.

On August 17, 1894, Hardy Campbell won the first five races atJerome Park Racetrack. All five of his winners were ridden byHall of Fame jockeyWillie Simms.^[2][3]

In January 1895 a number of prominent Americans sent a stable of horses to compete inEngland. Mike Dwyer andRichard Croker, with whom Dwyer operated a racing partnership, also sent a stable of horses under the care of Campbell and jockeyWillie Simms. The American trainer caused a sir among his English counterparts when he timed his horses' workouts, something that all race conditioners were then doing inNorth America andAustralia.^[4] In April 1895, Campbell and Simms won the Crawford Plate atNewmarket Racecourse with a horse name Utica who was renamed in England as Eau de Gallie. Although Hardy Campbell Jr. remained head trainer for Mike Dwyer throughout his short life, he only trained for Richard Croker until the Dwyer-Croker partnership was dissolved on May 17, 1895, in England.^[5]

Back in the United States, in 1896 Campbell won theKentucky Derby with Ben Brush and got his secondAmerican Classic win in the 1898Preakness Stakes withSly Fox, the latter a colt owned by Mike Dwyer's eldest son,Charles. Campbell Jr. trained Mike Dwyer's fillyCleophus toAmerican Champion Three-Year-Old Filly honors in 1896 and 1897.^[6]

In early June 1898, the then thirty-four-year Campbell fell ill withpneumonia.^[7] A husband and father of two, he died two weeks later on June 24. In their obituary, theNew York Times called him "an excellent judge of horses" and that it was "due in a great measure to his ability as a trainer that M. F. Dwyer was so successful with his horses.^[8][9]

A few months later his despondent sixty-year-old father, further distressed by a disagreement with a grandson over a horse owned by his son, attemptedsuicide.^[10]
