Thomas Curtis Clarke
American engineer (1827–1901)

Thomas Curtis Clarke (September 16, 1827 – June 15, 1901) was an American railway engineer, builder and author best known for a series of cast iron bridges in the United States. While living and working in Port Hope, Ontario, his firm won the contract to build the east and west blocks of the Canadian Houses of Parliament.
Life
Clarke was born in Newton, Massachusetts on September 16, 1827 and as a boy he attended the Boston Latin School. He enrolled at Harvard University, graduating in 1848 with a Bachelor of Arts degree in engineering, working under Captain John Child.
In 1873, Clarke was elected as a member to the American Philosophical Society.
Thomas Curtis Clarke died in New York City on June 15, 1901, and is buried in Port Hope, Ontario, Canada.
The world of today differs from that of Napoleon Bonaparte more than his world differed from that of Julius Caesar, and this change has chiefly been made by engineering.

Why this record matters
“Thomas Curtis Clarke” is worth following because a concise public description often conceals a longer documentary argument. Here, Thomas, Curtis and Clarke provides the most credible route into that argument.
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 Sep 6, 2026. The linked authority identifier is Q7788758. VIAF identifies the subject as 36751272. The Library of Congress control number is no2009004363. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1827, 1901, 1848 and 1873.
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.
