Ammi B. Young
American architect

Ammi Burnham Young (June 19, 1798 – March 14, 1874) was a 19th-century American architect whose commissions transitioned from the Greek Revival to the Neo-Renaissance styles. His design of the second Vermont State House brought him fame and success, which eventually led him to become the first Supervising Architect of the U.S. Treasury Department. As federal architect, he was responsible for creating across the United States numerous custom houses, post offices, courthouses and hospitals, many of which are today on the National Register. His traditional architectural forms lent a sense of grandeur and permanence to the new country's institutions and communities. Young pioneered the use of iron in construction.
Early life and works
Born in Lebanon, New Hampshire, Ammi B. Young was the son of Rebecca Burnham and Samuel Young, a builder-designer of churches, courthouses and academy buildings in the Lebanon area. He showed a talent for mathematics and drawing, and at the age of 14, began work in his father's trade. In 1823, Young married his first wife, Mary Hough of Lebanon. Like many aspiring builder-designers of the day, he learned the classical orders from pattern books by New England architect Asher Benjamin. Indeed, his design for the Federal style First Congregational Church, built in Lebanon in 1828, borrows significantly from Plate K of The American Builder's Companion.

Why this record matters
The phrase “american architect” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The entry’s evidential value lies in the named roles, institutions and publications that can be tested against primary documentation. The source revision retrieved here is dated Jul 30, 2025. The linked authority identifier is Q4747234. VIAF identifies the subject as 1641168. The Library of Congress control number is n90720591. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1798, 1874, 1823 and 1828.
Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
