Rosario Candela (March 7, 1890 – October 3, 1953) was an Italian American architect who achieved renown through his apartment building designs in New York City, primarily during the boom years of the 1920s.

As architectural historian Cristopher Gray has written: "Rosario Candela has replaced Stanford White as the real estate brokers' name-drop of choice.

[6] Keenly aware of his talent, he went so far as to erect a velvet rope around his drafting table to prevent other students from copying his designs.

[8] During this period, the West side was undergoing an intense transformation from an area of primarily single-family homes to one characterized by the apartment buildings.

Many apartments were constructed as duplex residences with grand entry foyers; curved, freestanding stairways; and dramatic public rooms.

That triplex, of more than 20,000 square feet (1,900 m2), "had, depending on who was counting, anywhere from 23 to 37 rooms, the discrepancy caused by such questions as whether one included hallways and foyers the size of ballrooms, servants quarters, and the fourteen bathrooms".

[citation needed] Candela began studying cryptography in 1930 after learning about the accomplishments of the Army Signal Corps in WWI.
