Syms Covington (1816–1861) was a fiddler and cabin boy on HMS Beagle who became an assistant to Charles Darwin and was appointed as his personal servant in 1833, continuing in Darwin's service after the voyage until 1839. Originally named Simon Covington, he was born in Bedford, Bedfordshire, England, the youngest child of Simon Covington V and Elizabeth Brown. After Covington's trip on the Beagle, he then emigrated to Australia and settled as a postmaster, marrying Eliza Twyford there.
When he was fifteen years old, Syms Covington became "fiddler & boy to Poop-cabin" on the second survey expedition of HMS Beagle, which left England on 27 December 1831 under the command of captain Robert FitzRoy.
Covington kept a journal of the voyage, and in September 1832 at Bahía Blanca in South America he noted wildlife found there, including a find of rhea eggs, and giant fossil bones of the megatherium which were collected and sent to England. It is not clear if he was assisting Charles Darwin with this work, but FitzRoy's later account suggests that both Darwin and Covington worked at excavating the fossils, and on 3 November Darwin arranged some clothing for Covington.
On 29 April 1833, Darwin and Covington landed and took up residence ashore at Maldonado, Uruguay, while the Beagle went elsewhere on survey work. After an excursion into the interior lasting twelve days, they spent several weeks at Maldonado preparing the collections to be sent back to England. In a letter home started on 22 May, Darwin told his father that he had decided to take Covington on as a servant –
The following business piece is to my Father: having a servant of my own would be a really great addition to my comfort,—for these two reasons; as at present, the Captain has appointed one of the men always to be with me, but I do not think it just thus to take a seaman out of the ship;—and 2nd when at sea, I am rather badly off for anyone to wait on me. The man is willing to be my servant, & ALL the expences would be under £60 per annum. I have taught him to shoot & skin birds, so that in my main object he is very useful.
