Brown, Samuel, chemist, grandson of the author of the Self-interpreting Bible, was born in 1817 at Haddington. Educated at the Edinburgh High school and University, he graduated M.D. in 1839. He devoted his attention chiefly to chemistry, and became possessed of the idea that elements usually considered simple and primary might be resolved into one another. He also contributed to general literature, publishing in 1850 the tragedy of Galileo. His Lectures on the Atomic Theory, and Essays Scientific and Literary were published in 1858. He died in 1856 in Edinburgh.
