If you ever saw a refrigerated truck with produce drinks or food headed to your local grocery. You can give all thanks and credit to Frederick McKinley Jones. A True inventor, Jones filed for more than 60 patents throughout his life, such as roof-mounted cooling systems that refrigerated goods on trucks for transportation in the 1930s.
His most noted patent invention came in 1940, co-founding Thermo Control Company, now known as Thermo-King. The company was necessary during World War II, and his cooling systems preserved blood, food, and other supplies during the war.
While the majority of his patents pertained to refrigeration technologies, others related to X-ray machines, engines, and sound equipment. Jones recognized for his achievements both during his lifetime and after his death. In 1944, he became the first African American elected to the American Society of Refrigeration Engineers. Jones died of lung cancer in Minneapolis, Minnesota, on February 21, 1961. In 1991, President George H.W. Bush awarded the National Medal of Technology posthumously to Numero and Jones, presenting the awards to their widows at a ceremony held in the White House Rose Garden. Jones was the first African American to receive the prize, though he did not live to receive it. He was inducted into the Minnesota Inventors Hall of Fame in 1977, according to Biography.com.
