Donald Roebling (1908-1959) was an engineer, philantropist, and inventor who created the Alligator, a tracked vehicle to be used for rescues after hurricanes in Florida. This vehicle was tested by and developed for the United States Marine Corps to be used as an amphibious assault vehicle during World War II. His great grandfather John A. Roebling designed the Brooklyn bridge and died early in the building process, and his grandfather Washington Roebling and his wife Emily oversaw and completed it. Donald Roebling built his mansion, Spottis Woode, in Clearwater, Florida in 1929, and it was added to the National Register of Historic Places in 1979.
Karl "Bucky" Roebling (1929-1009) was an author of several books on military history.
