How many of the Piccirilli brothers helped carve the Lincoln Memorial located in Washington D.C. USA?

The Piccirilli brothers were an Italian family of renowned marble carvers and sculptors who carved many of the most significant marble sculptures in the United States, including Daniel Chester French’s colossal Abraham Lincoln (1920) in the Lincoln Memorial, Washington, D.C.

In 1888, Giuseppe Piccirilli (1844–1910), a well-known stone carver in Massa, a province in the Tuscany region of central Italy, brought his family to New York City and set up a workshop next to their home in the Bronx that eventually occupied an entire city block. Giuseppe came from a long line of stone carvers, unbroken since the days of the early Renaissance.

All six of Giuseppe's sons—Ferruccio (1864–1945), Attilio (1866–1945), Furio (1868–1949), Masaniello (aka Thomas) (1870–1951), Orazio (aka Horatio, Horace) (1872–1954) and Getulio (1874–1945) were trained as marble cutters and carvers.

At that time most prominent sculptors created their original work in clay. A plaster model was then sent to the Piccirilli Brothers who then carved it from stone, usually marble. The brothers were the carvers of choice for many American sculptors of the time, also creating architectural details and embellishments for many public and private buildings.

The Lincoln Memorial is a U.S. national memorial that honors the 16th president of the United States, Abraham Lincoln. Its sculptor, Daniel Chester French, supervised all six of the Piccirilli brothers in its construction, and it took four years to complete.
