Early life and education
Cook was born in Litchfield County, Connecticut to Henry Cook and his wife Hannah Benham.
Enlisting in the Continental Army at the age of sixteen, Cook fought at Brandywine and in the Virginian campaign, and was present at Charles Cornwallis' surrender. He received an honorable discharge signed by George Washington on June 12, 1784.
Later life and death
Following the war, Cook became a farmer and married Hannah Curtis. They had seven sons and three daughters.
Cook died at the age of 106 and was buried with full military and Masonic honors. He was one of seven American Revolutionary War veterans who, having survived into the age of photography, were featured in the 1864 book The Last Men of the Revolution, which gives many details of his life. He was the last survivor of 2nd Continental Light Dragoons and was one of only four Revolutionary War veterans to see the start and end of the American Civil War. At the time of his death, only two other revolutionary veterans (Samuel Downing and John Gray) were still alive.
