Detlef Lienau

Detlef Lienau (February 17, 1818 Uetersen – August 29, 1887) was a German architect born in Holstein. He is credited with having introduced the French style to American building construction, notably the mansard roof and all its decorative flourishes. Trained at L’Ecole des Beaux-Arts in Paris, he designed virtually every type of Victorian structure—cottages, mansions, townhouses, apartment houses, hotels, tenements, banks, stores, churches, schools, libraries, offices, factories, railroad stations, and a museum. Lienau was recognized by clients and colleagues alike as one of the most creative and technically proficient architects of the period, and was one of the 29 founding members of the American Institute of Architects.
