In 1933 Lammot du Pont married for the 4th and final time to Margaret Flett. Lammot died in 1952 while Margret died in 1968. In 1968 Margret established a charitable organization called the Marmot Foundation.

I have a picture of the Marmot and also a picture of the "gambling parlor" inside the yacht. When I get the time, I'll be posting all to my website. Can anyone explain the Du Pont burgee? What is that creature curled around an up pointing arrow?
