Known as Mr. Imagination, he was born Gregory Warmack in 1948. Raised in Chicago by a large religious family many of his earliest commissions came from his church. As a child he made earrings, decorative pins, woodcarvings, and hats that he sold on the street. In 1978, Warmack had a near death experience where he was shot at point blank range while being mugged. He claims to have had an out of body experience that sent him back in time to observe ancient civilizations. This episode encouraged him to make a lifelong commitment to creating regenerative art that heals. Warmack began referring to himself as "Mr. Imagination" around 1980 to highlight his charismatic artistic alter ego. His work explores self-identity, immortality, and pride in Black culture. With no formal training his signature use of sandstone and elaborate bottle cap creations have ushered Warmack into international success.
His work was featured in the exhibition, On Their Own: Selected Works by Self-Taught African American Artists, January 31 through June 12, 2005 at the Anacostia Community Museum, Smithsonian Institution.
