Donald Wyman

Donald Wyman (1904 — 6 December 1993) was an American horticulturist, the head of horticulture at Harvard University's Arnold Arboretum from 1935 to 1970.

He took a bachelor's degree in horticulture from Pennsylvania State College (1926) and a master's in forestry (1933), then a PhD in horticulture at Cornell University (1935). He joined the Arboretum in 1935 and served for six months without salary in the depths of the Great Depression before being named horticulturist in 1936. Wyman served as president, director, and trustee of the American Horticultural Society.

At the Arnold Arboretum he departed from the original method of planting by botanical association, to mark vistas and turns with specimen trees, and was energetic in acquiring seeds of many species that he introduced to American horticulture. He retired in 1970.

He received the George Robert White Medal from the Massachusetts Horticultural Society (1970), the Liberty Hyde Bailey Medal from the American Horticultural Society, the Veitch Memorial Medal from the Royal Horticultural Society (1969) and the Medal of Honor from the Garden Club of America (1965). The widely planted crabapple Malus "Donald Wyman" was named for him upon his retirement in 1970.
