Input: Question: When was the school from which the person Dall named Gustavus for graduated founded? Passage:In 1793 George Vancouver named Point Adolphus (at the northern tip of Chichagof Island, and today a well-known humpback whale feeding area) after Adolphus Frederick, seventh son of King George III. In 1878, W.H. Dall, while working on a coastal survey, saw "Adolphus" on the map and assumed it was for Swedish king Gustavus Adolphus. The point across Icy Strait from Point Adolphus at the mouth of Glacier Bay was not named on the map, so Dall called it "Gustavus". Another possibility is that Dall named Gustavus for Gustavus C. Hanus, a U.S. Naval Academy graduate who had extensive experience throughout southeast Alaska, and both Dall and Hanus served with the Coast Survey in Alaska. Hanus laid out the first streets in Juneau and helped quell the trouble in Klukwan in 1881.
