Captain Alexander McDougall (March 15, 1845 – May 27, 1923) was a Scottish-born American seaman who built the whaleback style of cargo and excursion ship. In 1880, he designed a ship that he felt could withstand the worst lake water and carry the greatest cargo in the least depth of water. In 1917 he founded McDougall Duluth Shipbuilding Company to build World War I ships.[1][2][3][4]
