The Linnean Society of New South Wales promotes the Cultivation and Study of the Science of Natural History in all its Branches and was founded in Sydney, New South Wales (Australia) in 1874 and incorporated in 1884.
[4] The establishment of the Society was largely due to the dedication and financial support of its first President, Sir William Macleay.
Joseph James Fletcher was director and librarian (this title was afterwards changed to secretary) from 1885 and edited 33 volumes of the Proceedings of the society.
In September 1882, a fire destroyed the library and a part of the scientific material of the society.
In 1903, the Society created the Macleay bursary, which has since helped many students of the University of Sydney to continue their studies and to engage of the significant research tasks in the fields of botany, zoology or geology.
