Arnold Arboretum is established.

(March) Designed by Frederick Law Olmsted and Charles Sprague Sargent, it is located on land donated by Benjamin Bussey near today’s 125 The Arborway. It is named for James Arnold, who left a bequest to create, “An arboretum which shall contain, as far as practicable, all the trees [and] shrubs … either indigenous or exotic, which can be raised in the open air.” Charles Sprague Sargent is the first director and serves until 1927. Owned initially by Harvard University, it is purchased by the city of Boston on December 30,1882, and becomes the first public arboretum in the U.S., although leased back to Harvard for 1,000 years for $1 per year. The arboretum today contains more than 14,000 species of flowers, shrubs and trees from all over the world.
