H. H. Hunnewell

Horatio Hollis Hunnewell (July 27, 1810 – May 20, 1902) was an American railroad financier, philanthropist, amateur botanist, and one of the most prominent horticulturists in America in the nineteenth century. Hunnewell was a partner in the private banking firm of Welles & Co. Paris, France controlled by his in-laws, which specialized in trade finance between the two countries. Practicing horticulture for nearly six decades on his estate in Wellesley, Massachusetts, he was perhaps the first person to cultivate and popularize rhododendrons in the United States.
