Alexander Thomson of Banchory, Scottish jurist, agriculturalist and religious activist (died 1868)

Alexander Thomson of Banchory FRSE (1798–1868) was a 19th-century Scottish advocate, agriculturalist, antiquary, author, philanthropist and traveller. He owned an estate at Banchory-Devenick in Aberdeenshire. After qualifying as an advocate in Edinburgh he returned to the estate and did not pursue a career at the bar preferring to follow the life of a country gentleman. He travelled extensively in Europe, spending many years studying overseas. He settled crofters on his estate and planted many trees. His position in life allowed to give time to many interests including antiquarian studies, geology, biology and social reform. He attempted to unite Marischal and King's Colleges in Aberdeen University. At the Disruption he sided with the Free Church and was a prominent leader in that cause. He died in 1868 and bequeathed a sizeable museum and collection of books to the church. He also gave a substantial amount of money to set up a Free Church College in Aberdeen.
