In 1949, Adickes travelled to France to study under Fernand Léger. After two years, he returned to Texas and began presenting his work. In 1955, Adickes was commissioned to paint a large historical mural of the city of Houston for the then-new Houston Club. That fall, he was hired to teach in the Art Department of the University of Texas at Austin.
In 1983, after being a fulltime painter and art instructor for more than two decades, Adickes was commissioned to make his first monumental sculpture. He created the Virtuoso, a 36-foot (11m) steel and concrete statue of a string trio. It is displayed in Houston. In 1986, he created Cornet as a stage prop for the New Orleans World Fair. In 1994, he created A Tribute to Courage in memory of Houston's namesake, Sam Houston. In 2004, he created 43 large busts of American presidents at Presidents Park, Virginia. In 2006, he erected 60-foot (18m) statue of Stephen F. Austin in Brazoria County, Texas. The busts installed at Houston's American Statesmanship Park were created in 2008 and donated to Harris County in 2012. In 2012, he turned his old high school in Huntsville into the Adickes Art Foundation Museum.
