Frank E. Kirby (July 1, 1849 – August 25, 1929)^[1] was a naval architect in the Detroit, Michigan (United States) area in the early 20th century. He is widely regarded as one of the greatest naval architects in American history.

Kirby was a marine engineer and architech. "He prepared plans and specifications for the refitting of the Grant, Sherman, Sheridan, Logan, and Thomas, and [was] a consulting engineer... of the transport branch of the Quartermaster's Department."^[2]

Kirby mostly specialized in paddle-wheel and steamship design. Perhaps his most famous vessel, Tashmoo, was a paddle-wheeler launched on New Year's Eve, 1899. She was constructed by the Detroit Shipbuilding Company in Wyandotte, Mich., for the White Star Steamship Co. of Detroit. The 306-foot vessel made her maiden voyage on June 9, 1900. She would become one of the best known - and most beloved - excursion steamers on the Great Lakes.

Kirby also is well-renowned for his design of the "Bob-Lo boats" - the Columbia and the Ste. Claire. Boblo Island was a major amusement park destination for residents of southeast Michigan (and southern Ontario, Canada) throughout most of the twentieth century. He is also considered the father of modern ice-breaking technology. He designed the D&C Navigation Co.’s armada of stately night boats, including the City of Detroit III.
