Henry Drummond (1851–1897) was born in Stirling,
Scotland, and was educated at Edinburgh University. In 1877, he
became a lecturer on natural science at the Free Church College of
Glasgow. Drummond was a geologist and an explorer, and he spent a
portion of time away from the classroom on scientific expeditions.
As a Christian, he combined his knowledge of science with his
understanding of God the Creator and His diverse creations. Beyond
his work as a scientist, Drummond desired to see men and women come
to Christ. He accompanied Dwight L. Moody on many of his revival
missions in England and Ireland, and he presented an address on
biblical love during this time that deeply affected Moody. Drummond
wrote several works on science, but his most famous and enduring
book, based on that address on love, is The Greatest Thing in
the World.
