Born in Warsaw in 1924, Adam (Grochowski) Grant was initially discouraged by his family from pursuing a professional art career because art would "never earn the price of your bread." Later, when Adam was sent to the Nazi concentration camps Auschwitz and Mauthausen, he literally traded his art for bread, enabling him to survive.

Adam survived the camps and later emigrated to the United Sates in 1950, securing a job with the Palmer Paint Company in Detroit, Michigan, that had begun to produce the now-legendary Paint By Number kits. There, Adam met fellow designer and future wife, Margaret "Peggy" Brennan. The couple married shortly before the business was sold to the Toledo-owned Craft Master company. Americanizing his name, the new Mr. and Mrs. Grant moved to Toledo, Ohio, where Peggy managed his fine art career and Adam painted until his death in 1992.

During his lifetime, Adam Grant’s fine art paintings were widely exhibited in galleries, as well as juried and solo exhibitions throughout the world, frequently garnering prestigious awards, including the American Painters in Paris Exhibit; Columbus Museum of Art's Best of Show, numerous top honors in the Toledo Area Artists Exhibition and the Toledo Museum of Art Roulet Medal. He was the featured painter in the January 1973 edition of American Artist. In recent years, Peggy, the executrix of his artistic estate, has organized and facilitated exhibits of his work in the Midwestern United States, Poland and Saudi Arabia.

His work is part of many prestigious private, corporate and public collections, including The Collegium Maius Museum-Krakow, Poland; Butler Institute of American Art, Youngstown, Ohio; Midwest Museum of American Art, Elkhart, Indiana; Bowling Green State University, Ohio; Monroe Community College, Michigan; The University of Toledo; Toledo Federation of Art Societies; the Polish Embassy in Riyadh, Saudi Arabia; and Auschwitz Museum, Poland. In 2011, Grant’s work was accepted as a part of the permanent collection at the inauguration of the Polish History Museum in Warsaw, forming the symbolic return of Adam Grochowski-Grant to his native city.
