Henry Engelbert was an architect best known for buildings in the French Second Empire style, which emphasized elaborate mansard roofs with dormers. New York's Grand Hotel on Broadway is the most noteworthy extant example of Engelbert's work in the French Second Empire Style. Also, many of his commissions were Lutheran or Roman Catholic churches.

Engelbert was born in Germany in 1826. In 1852, he established his practice in partnership with John Edson, and their office was at 85 Nassau Street in New York City. The latter years of his career were spent in Detroit, where he died in 1901.
