As early as 1904 Lamb was credited with renovations for two existing theaters in the city: the Weber and Fields Music Hall at 1215 Broadway, and the Dewey Theater on East 14th Street, the latter owned by Tammany Hall figure "Big Tim" Sullivan. His first complete theater design was the City Theatre, built on 14th Street in 1909 for film mogul William Fox. His designs for the 1914 Mark Strand Theatre, the 1916 Rialto Theatre and the 1917 Rivoli Theatre, all in Times Square, set the template for what would become the American movie palace.
