Input: Question: In which city did Robert Henderson attend college? Passage:Henderson was born in 1778, the son of prominent naval officer Captain William Henderson of Aberdeen, an important landowner in Forfarshire. Educated at Marischal College, Henderson followed his father into the British Royal Navy in 1792 as a midshipman in HMS Southampton shortly before the outbreak of the French Revolutionary Wars. Serving during the war, Henderson became a lieutenant in 1799 aboard the sloop HMS Osprey and was still aboard her during the successful invasion of Saint Lucia in 1803. Later in the year, Osprey attacked a schooner off Trinidad and Henderson, who led the boarding party, was very seriously wounded. The following year, still on Osprey, Henderson led another boarding party that captured the French privateer Resource off Trinidad. For this service, Henderson was awarded a sword by the Lloyd's Patriotic Fund of London and moved to the ship of the line HMS Centaur.
