Life

John Webb Seymour was the fourth son of Webb Seymour, 10th Duke of Somerset and Mary Anne, Duchess of Somerset (née Bonnell).

He was educated at Edward Meyrick's school in Ramsbury. At Oxford he was interested in anatomy and, especially, chemistry. In his rooms, he set up a chemical laboratory. After graduation, he went to Edinburgh and became friends with Francis Horner, the philosopher Thomas Brown and John Playfair. Seymour took trips with Playfair on a number of occasions studying the geology of Scotland and a few times in England. Seymour also learned mathematics from Playfair and studied political economy as well as Bacon's De Augmentis Scientiarum and Novum Organum.

In 1799, he was elected a Fellow of the Royal Society of Edinburgh. His proposers were Sir James Hall, 4th Baronet, Andrew Duncan, the elder, and Robert Kennedy. He served as Vice President to the Society 1802 to 1805. In 1802 he was elected a Fellow of the Royal Society of London.

Upon the threat of Napoleonic invasion of England, Seymour from 1803–5 took command of a company of volunteers in Devonshire.

In 1805 he returned to Edinburgh and settled there with his brother at 2 Abercromby Place until the end of his life, with occasional trips to England. He published a few pages on geology but nothing else.

He was unmarried and had no children.
