[citation needed] One of his brothers was Samuel Fisk Green, a medical missionary of the American Ceylon Mission in Sri Lanka.

The Republican-led New York State Legislature began to institute measures to control the municipal affairs of the largely Democratic metropolitan region; one such act created the Central Park Commission.
In April 1858, Olmsted and Vaux's Greensward Plan for Central Park was chosen by the CPC, thanks largely to Green's influence.
With Green's coaxing, the legislature began to expand the CPC's authority, transforming it into the city's first comprehensive planning body.
