Harry, as he was known by his numerous brothers and sisters, migrated to the United States about 1877/8 where he apprenticed with his oldest brother John William Kitson. William Kitson was in business with another Englishman Robert Ellin; their firm, Ellin & Kitson, were identified as architectural sculptors. They specialized in interior carving and wood work in commercial structures and churches. Some buildings they worked on were the Equitable Building, the Tilden Mansion, the Astor Memorial Redos and the William K. Vanderbilt House.
Harry and Samuel James Kitson, the next oldest brother, were both associated with Ellin & Kitson doing sculptural work. According to family oral history, In 1882, William, now quite successful, encouraged and financially provided for Harry Kitson to move to Paris where he studied at the École des Beaux-Arts under the sculptor Jean-Marie Bonnassieux and sculptor Dumont.
Kitson also was enrolled in the École Nationale Supérieure des Arts Décoratifs, studying under Millet and Ganter. He returned first in 1884/5 to New York City to his eldest brother William's business.
In 1886 he moved to Boston where his sculptor brother Sam had established a studio. Once there Kitson received numerous commissions and began teaching. His students included portrait sculptor Leila Usher.
John William Kitson died in 1888 and Samuel James had returned to Boston after a stay in Washington DC. The youngest brother Robert Lewellen Kitson, a water-colorist, joined his older brothers in Boston about 1902.
In 1893, Henry married Theo Alice Ruggles, a former student of his, who went on to have a successful career of her own as Theo Alice Ruggles Kitson. Theo and Harry had three children: Theo (called Babs), John, who became a civil engineer, and Dorothy. None of the children had issue. The noted sculptor Gaston Lachaise worked in his atelier.
Many of Henry Hudson Kitson papers are in the Archives of American Art in Washington, D.C. as well as the New York Historical Society.
He was the author of numerous public monuments, and left behind his home, Santarella, in Tyringham. The home, which Kitson modified extensively, was recently restored and now operates as a special events venue as well as providing overnight accommodation.
Kitson remained a British subject for his entire life.
