Benjamin Henry Boneval Latrobe (May 1, 1764 - September 3, 1820) was a British subject and neoclassical architect who emigrated to the United States. He was one of the first formally trained, professional architects in the new United States, drawing on influences from his travels in Italy, as well as British and French Neoclassical architects such as Claude Nicolas Ledoux. In his thirties, he emigrated to the new United States and designed the United States Capitol, on "Capitol Hill" in Washington, D.C., as well as the Old Baltimore Cathedral or The Baltimore Basilica, (later renamed the Basilica of the National Shrine of the Assumption of the Blessed Virgin Mary). It is the first Roman Catholic Cathedral constructed in the United States.

Latrobe returned to England in 1784, and was apprenticed to John Smeaton, an engineer known for designing Eddystone Lighthouse. Then in 1787 or 1788, he worked in the office of neoclassical architect Samuel Pepys Cockerell for a brief time. In 1790, Latrobe was appointed Surveyor of the Public Offices in London, and established his own private practice in 1791. Latrobe was commissioned in 1792 to design Hammerwood Park, near East Grinstead in Sussex, his first independent work, and he designed nearby Ashdown House in 1793. Latrobe was involved in construction of the Basingstoke Canal in Surrey, together with engineers John Smeaton and William Jessop. In spring 1793, Latrobe was hired to plan improvements to the River Blackwater from Maldon to Beeleigh, so that the port of Maldon could compete with the Chelmer and Blackwater Navigation, which bypassed the town. The project lasted until early 1795, when Parliament denied approval of his plan. Latrobe had problems getting payment for his work on the project, and faced bankruptcy.  In February 1790, Latrobe married Lydia Sellon, and they lived a busy social life in London. The couple had a daughter (Lydia Sellon Latrobe) and a son (Henry Sellon Boneval Latrobe), before she died giving birth during November 1793. Lydia had inherited her father's wealth, which in turn was to be left to the children through a trust with the children's uncles, but never ended up going to the children. In 1795, Latrobe suffered a breakdown and decided to emigrate to America, departing on November 25 aboard the Eliza.  In America, Latrobe was known for his series of topological and landscape watercolors; the series started with a view of the White Cliffs of the south coast of England viewed from the Eliza. The series was preceded by a watercolor of East Grinstead, dated September 8, 1795.
