John Hamilton Pagan, Scottish minister and plant collector, was the son of John Pagan, Doctor of Divinity and amateur botanist, and his wife Margaret Wiseman, born Lang. He studied at the
University of Glasgow and qualified as Master of Arts (MA) in 1891 and Bachelor of Divinity (BD) in 1894. He came to South Africa in or before 1901, for in that year he requested the authorities of the Orange River Colony (now the Free
State) to appoint him as a marriage officer. By 1908 he was a minister in the
Presbyterian Church in South Africa and resided in Kimberley. Just before his
death he wrote The flower of the hidden
crown, and other letters to boys and girls from a South African stoep
(Edinburgh, 1913; 4th ed., 1922), a collection of letters originally
published in the Presbyterian Churchman.
In 1910 Pagan collected, dried and named a number of plants at
Klein Boetsap (west of Warrenton, in the Northern Cape) for the McGregor Museum
in Kimberley. Two years later he presented the museum with a large number of
mounted and named plants from De Aar. He was survived by his wife Agnes Elizabeth Leslie, born Blair.
