I’m in the midst of reading *Coral and Brass* by General Holland “Howlin’ Mad” Smith, his account of his many years of helping to shape the modern Marine Corps. Last night I was reading how the Marines, as WWII broke out, had wanted an amphibious tank, and that their wishes were fulfilled with the development of the amtrac, or LVT (Landing Vehicle Tracked) – invented as the “Alligator” by one Donald Roebling.

That name caught my eye. A quick Web search, and I knew: he was the great-grandson of John Roebling, and grandson of Washington and Emily Roebling, the father-son-daughter-in-law combination that envisioned and built the Brooklyn Bridge.

What a great family.
