Frederick McKinley Jones is the reason why trucking companies around the world can transport perishable goods because he invented the portable refrigeration technology that makes it possible. The world-renowned African-American inventor, entrepreneur, winner of the National Medal of Technology, and National Inventors Hall of Famer was awarded 61 patents during his life. His African American mother abandoned him and his Caucasian father John Jones at a young age.

Working for the railroad Jones struggled to care for Frederick and sent him to live with Father Ryan, a Catholic priest, so he could be educated. Ryan noticed the young Jones had an uncanny ability in electronics and mechanics and encouraged him to perfect this skill. Jones attended school and earned his keep by working around the church doing various jobs until his father died. At age 11 (6th grade) he quit school and moved to Hallock, Minnesota in 1912 where he got his first job working as an automobile mechanic at age 14.

The only time the self-taught mechanic left home was to serve in the Army during World War I. When he returned in 1930 he began to master working with electronics. He got so good he built a transmitter for Hallock's new radio station and picked up another patent for inventing a device that combined sound with motion pictures.

Jones would later move to Minneapolis and began working with Joseph A. Numero. Numero owned Cinema Supplies Inc. and hired Jones to help improve the sound on his companies equipment. In 1938, Jones designed a portable air-cooling device for trucks that would allow them to carry perishable foods. By 1940 he received a patent for his invention, Numero sold his movie sound equipment to RCA and the two co-founded Thermo King (now known as Thermo King Corporation.)

By 1949, refrigeration innovations by Frederick M. Jones became a $3 million business! Transporting perishable goods by way of long-haul trucking exploded and expanded to delivering refrigerated cargo by other means of transportation such as rail, air, and sea. During World War II, portable cooling units designed by Jones were used at army hospitals and on open battlefields to store blood, medicine, and food. Amazingly forty of the 61 patents awarded by Jones, were for refrigeration equipment.

In 1944 Jones became the first African American elected into the American Society of Refrigeration Engineers. He served as a consultant for the U.S. Department of Defense and the Bureau of Standards in the 50's. Jones died at age 67 in Minneapolis in 1961 of Lung Cancer. In 1977 he was inducted into the Minnesota Inventors Hall of Fame. In 1991, both Jones and Numero were awarded the National Medal of Technology by President George Bush. Their widows received the awards at a ceremony in the White House Rose Garden.
