Haldane, Robert (1764-1842), religious writer and preacher, was born in London. After serving three years in the navy, he continued his education at Edinburgh. In 1798 he sold his estate at Airthrey, and, having left the Church of Scotland, soon after set up Congregational tabernacles in Edinburgh. He afterwards adopted Baptist views, and alienated many of his followers. He spent large sums on his religious work, and in 1816-17 preached with great success in Geneva and Montauban. He was the author of two widely-circulated works, The Authenticity and Inspiration of the Scriptures and Exposition of the Epistle to the Romans. His brother James (1768-1851) was associated with him in his work, and also became known as a controversialist, especially by his attack on the doctrines of Edward Irving.
