Theodore Roosevelt VI (born circa 1976), known as Theodore Roosevelt V, is an American businessman and environmentalist. Theodore is a great-great-grandson of 26th U.S. President Theodore Roosevelt and through his ancestor Cornelius Van Schaack Jr., he is a descendant of the Schuyler family. His name suffix varies since President Roosevelt's father was Theodore Roosevelt Sr., though the same-named son did not commonly use a "Jr" name suffix. Hence, President Roosevelt's son is referred to as "Junior", though he was actually Theodore Roosevelt III, and the confusion regarding the names' suffixes continues to this day.
Theodore Roosevelt V was born to Theodore Roosevelt IV (born 1942), investment banker, and Constance Lane Rogers. He is a great-great-grandson of US President Theodore Roosevelt. As an Oyster Bay Roosevelt, and through his ancestor Cornelius Van Schaack Jr., he is a descendant of the Schuyler family.
He graduated from Deerfield Academy and Princeton University with a Bachelor of Arts degree in 1998 and Stanford's Graduate School of Business with an MBA.
