Alexander W. Livingston (1821–1898) was an American horticulturist and seed company founder. He developed some of the first tomato varieties that were suitable for commercial production. The U.S. Department of Agriculture's 1937 yearbook declared that "half of the major varieties were a result of the abilities of the Livingstons to evaluate and perpetuate superior material in the tomato." Livingston's first breed of tomato, the Paragon, was introduced in 1870.[1][2]
