Jacob Post was born in Whitefriars, London, on 12 September 1774. His parents, John and Rosamund Post, enrolled him at the relatively new Ackworth School in Yorkshire, which was run by the Society of Friends.
By 1787 Post had moved to Islington and was writing on behalf of the emerging evangelical section of the Quakers. In 1812 he founded a local section of the Bible Society. In 1837, his eighteen-year-old son died. In the following year he published Extracts from the Diary of Frederick James Post under joint authorship.
Post's output includes two children's books, accounts of founders of the Society of Friends – George Fox and William Penn, the founder of Pennsylvania – and matters of religious dispute in his time.
