From Ohio History Central
Many horticulturalists attribute the modern tomato to Reynoldsburg, Ohio, resident Alexander W. Livingston. Livingston spent two decades breeding his "Paragon" tomato before succeeding in 1870. Tomatoes existed before Livingston, but they were small fruits with a sour taste. Livingston's Paragon was much larger and had a sweeter taste. Over the next twenty-eight years, Livingston developed more than thirty other varieties of tomatoes.
