Ziolkowski was born September 6, 1908, in Boston to Polish parents. Orphaned at the age of one when both his parents died in a boating accident, he grew up in a series of foster homes, and was raised by an Irish boxer. Although he never received any formal art training, his gifts as a sculptor began to show at an early age. After putting himself through Rindge Technical School, he became an apprentice to a Boston ship maker. He began to carve wood and by the age of 20 had become an accomplished furniture maker. His first marble sculpture, made in 1932, honored Judge Frederick Pickering Cabot, who had inspired him as a child growing up in the rough neighborhoods of Boston. Ziolkowski moved to New Britain, Connecticut, to begin life as a professional artist. He began to sell commissioned sculptures throughout New England and New York. In 1939, Ziolkowski was hired as a sculptor's assistant by Gutzon Borglum on his Mount Rushmore project. According to Lincoln Borglum, Gutzon's son, he was unhappy, having expected to be made the primary assistant. Instead, Lincoln was the primary assistant, and when Ziolkowski argued about his orders, Borglum fired him by telegram. A fistfight between Lincoln and Ziolkowski had to be broken up. His sculpture of Ignacy Jan Paderewski won first prize at the 1939 New York World's Fair. The resulting fame, as well as his familiarity with the Black Hills, prompted several Lakota Chiefs, including a Lakota elder named Henry Standing Bear, to write to him about a monument honoring Crazy Horse. Chief Henry Standing Bear of the Lakota wrote him, saying, "My fellow chiefs and I would like the white man to know the red man has great heroes, too." Ziolkowski met with the leaders shortly afterward and began planning a monument. Over the next few years, he conducted research and began planning the sculpture. He also met Ruth Ross, a young art enthusiast, who would later become his second wife. He put the project on hold when the United States entered World War II. He volunteered for service and joined the United States Army on May 17, 1943. He was wounded in 1944 at Omaha Beach in Normandy. He was discharged as a sergeant on November 5, 1945. In 1947 Ziolkowski moved to the Black Hills and began to search for a suitable mountain for his sculpture. He thought the Wyoming Tetons would be the best choice, where the rock would be better for carving, but the Lakota wanted the memorial in the sacred Black Hills on a -high mountain. The monument was expected to be the largest sculpture in the world. When completed, it would be high by long. Crazy Horse's head would be large enough to contain all the -high heads of the Presidents at Mount Rushmore. On June 3, 1948, the first blast was made, and the memorial was dedicated to the Native American people. In 1950, Ziolkowski met Ruth Ross, 18 years his junior, who was a volunteer at the monument. She became Ziolkowski's second wife that year. Work continued slowly, since he refused to accept government grants. Instead, as he personally stated on a guest appearance on the TV show "To Tell the Truth", he raised money for the project by charging seventy-five cents admission to the monument work area.
Last years and death
Ziolkowski continued his work until he died of acute pancreatitis at age 74 at the monument site in 1982. He was buried in an impressive tomb that he had built, with a huge steel plate on which he cut the following words, "Korczak; Storyteller in Stone; May His Remains; Be Left Unknown" at the base of the mountain. After his death, his widow, Ruth Ziolkowski, took over the project as director of the Crazy Horse Memorial Foundation. Ruth Ziolkowski died May 21, 2014, aged 87. All ten of their children and two of their grandchildren have continued the carving of the monument or are active in the Crazy Horse Memorial Foundation. The rocks that are blasted away are placed in a rock crusher and used for the roads at the complex.
