Maud S. was foaled on March 28, 1874 at Woodburn Farm, Kentucky, a light-red chestnut daughter of Harold 413 and Miss Russell. As a yearling she was sold to James Bugher of Ohio for $250, who named her Sadie Bugher. She was sold to Capt. George M. Stone in 1877 for $350. Stone renamed her Maud S. and placed her in the care of W. W. Bair during her entire career. After trotting a mile in 2:17 1/2 at Lexington, Kentucky in 1878, Maud S. was immediately bought by William H. Vanderbilt for $21,000. She was used as Vanderbilt's roadhorse until 1884, when she was returned to the turf to lower the record to 2:10 and was sold to Robert Bonner for $40,000. While in his stable she trotted her record mile in 2:08 3/4 at Cleveland, Ohio, this being the seventh time she had lowered the world record in six years. In 1885 she was permanently retired as a roadhorse and died on March 17, 1901 at the Shultshurst Farm in Port Chester, New York. Maud S. is buried in Tarrytown, New York, next to 1956 Immortal Dexter.
