Establishment
By act of the New York State Legislature, the New York Botanical Garden was established on April 28, 1891. The garden occupied part of the grounds of the Lorillard estate and a parcel that was formerly the easternmost portion of the campus of St. John's College (now Fordham University); the latter included three graves of the Fordham University Cemetery, which were then relocated. The stated purpose of the act was:
... for the purpose of establishing and maintaining a botanical garden and museum and arboretum therein, for the collection of and culture of plants, flowers, shrubs and trees, the advancement of botanical science and knowledge, and the prosecution of original researches therein and in kindred subjects, for affording instruction in the same, for the prosecution and exhibition of ornamental and decorative horticulture and gardening, and for the entertainment, recreation and instruction of the people.
As per the acts of incorporation, a board of directors would manage the NYBG. The board of directors included Columbia College's president and professors of biology, chemistry, and geology; the presidents of the Torrey Society, New York City Board of Education, and the Department of Public Parks' board of commissioners; the Mayor of New York City; and nine other members elected to the board. The legislation would provide 250 acres (100 ha) within Bronx Park to the NYBG, and enable the board of directors to construct a library and conservatory, if at least $250,000 was raised within five years. If this condition were reached, the city would then issue $0.5 million in bonds. The principal officers of the new corporation set up for the garden were Cornelius Vanderbilt II, Andrew Carnegie and J.P. Morgan, with Nathaniel Lord Britton as the new secretary.
Prominent civic leaders and financiers, including Vanderbilt, Carnegie, and Morgan, agreed to match the City's commitment to finance the buildings and improvements. By May 1895, the $250,000 in bonds had been raised but the plans had not been fully confirmed. The Board of Directors then asked landscape architect Calvert Vaux and his partner, Parks Superintendent Samuel Parsons Jr., to consult on site selection. The north end of Bronx Park was decided as the best location for the NYBG. By August 1895, the architects had started a survey on the site. Because the Bronx River and various small tributaries ran through the park, drainage was a major consideration. Though Vaux's preliminary layout was approved in October 1895, he died the following month. The topographical survey was completed in March 1896. The master plan was created by a team that included Britton & Parsons, as well as landscape engineer John R. Brinley, landscape gardener Samuel Henshaw, botanist Lucien Marcus Underwood, and architects Robert W. Gibson and Lincoln Pierson (the latter from the firm Lord & Burnham).
The LuEsther T. Mertz Library and Enid A. Haupt Conservatory were among the first structures at the NYBG to open. The Library was built between 1897 and 1900, and the Conservatory was built around the same time, being completed in 1902.
