He is known for funding the establishment of the Tuck School of Business at his alma mater, Dartmouth College.

In the following year, he resigned, shortly before the Franco-Prussian War, and joined the banking firm Munroe & Co., where he was made a partner in 1871.

[5] He retired from banking in 1881, and, in 1889, went to live as an expatriate in France, where he donated an art collection valued at $5 million, and funds for hospitals and other institutions.

In 1929, after solicitation from Ernest Martin Hopkins, the 11th President of Dartmouth, Tuck donated 600 shares of Chase National Bank, which was sold for $567,766.

The home was formerly owned by Empress Joséphine, wife of Napoléon Bonaparte, and Queen mother Maria Christina of the Two Sicilies, widow of King Ferdinand VII of Spain who lived there with her second husband Agustín Fernando Muñoz, Duke of Riánsares, until she sold the home in 1861 to Napoleon III.

[1] His funeral was held at the American Cathedral in Paris,[12] and he was buried alongside his wife at the Saint-Germain-en-Laye cemetery.

[1] In 1932, Tuck was made an honorary citizen of France, the highest honor the government could give.
