Frederick McKinley Jones

Early life

Jones was born in Covington, Kentucky, on May 17, 1893, to an Irish father and African-American mother. Little is known about his mother who left his life when Jones was a child. His father, John Jones, was a railroad worker who struggled to raise him on his own. Jones was raised by a Catholic priest, Father Ryan, at a rectory in Cincinnati, Ohio, near Covington. Father Ryan took in Jones around the age of seven, and two years later, John Jones died. Jones left school at age 11 after the sixth grade. He went to nearby Cincinnati, Ohio, working odd jobs including a role as a garage cleaning boy. By age 14, Jones was working as an automobile mechanic and was later named garage foreman. Jones was largely self taught.

Career

Mechanical engineer

In 1912, Jones moved to Hallock, Minnesota, where he worked as a mechanic on a 50000 acre farm. The farm was owned by James J. Hill, who was also owner of the Great Northern Railroad. Jones' proximity to Hill and the railroad facilitated his education in electricity and steam locomotive engines. Jones lived there for more than 20 years and would later say in a newspaper article that Hallock was a place "where a man … [was] judged more on his character and ability than on the color of his skin." He was locally known as "Casey" due to a remark by a railroad engineer he met while working at Hill Farm (see also Casey Jones). Jones received his engineering license at age 20. He later upgraded his license to the highest grade.

Army service

In the U.S. Army, Jones took part in World War I in an all-black unit until his mechanical skills were spotted, and he was promoted to sergeant working as an electrician and even teaching other soldiers. Jones performed the wiring necessary to equip his camp with electricity, telegraph, and telephone services.

Audiovisual work

After military service in World War I, Jones returned to Hallock. He worked as a mechanic while learning about electronics. Jones built a transmitter for the town's first radio station. He also invented a device to combine sound with motion pictures. This attracted the attention of local entrepreneur Joseph A. Numero of Minneapolis, Minnesota. Numero owned a company that manufactured audio equipment called Ultraphone Sound Systems Inc. and was later renamed Cinema Supplies Inc. He hired Jones in 1927 as an electrical engineer to improve the audio equipment made by his firm. Jones worked on converting silent movie projectors into audiovisual projectors. He also patented a ticket-dispensing machine for movie theaters.

Refrigeration

Around 1938, following a request by Numero, Jones began designing the Thermo Control Model A automatic truck refrigeration unit. Jones designed the portable air-cooling unit for trucks carrying perishable food to prevent spoilage. The Model A refrigeration equipment was attached to undercarriages of trucks. Chilled air was transported to the inside of the trailer via refrigerant tubing. Because Model A was too heavy, Jones later developed the Model B. The Model B was smaller and lighter, but not durable. In 1941, Jones completed development of the Model C, which was mounted to the front of the truck. It was compact, light, and withstood road travel vibrations. In 1939, Jones filed for a patent for the Model A and received a patent for it on July 12, 1949. Numero sold his movie sound equipment business to RCA and formed a new company in partnership with Jones, the U.S. Thermo Control Company (later the Thermo King Corporation) which became a $3 million business by 1949. Portable cooling units designed by Jones were especially important during World War II, preserving blood, medicine, and food for use at army hospitals and on open battlefields. Model C units were initially manufactured for military use, but following the war the units became available for commercial use as well.

Other inventions

Jones also developed a portable x-ray machine. He also developed an early prototype of a snowmobile. It was called a "snow machine" that attached skis to the undercarriage of an airplane fuselage and attached a propeller, and a sound track synchroniser (later selling the patent to RCA). An early radio service for local doctors were also counted among his inventions.

Distinctions and honors

During his life, Jones was awarded 61 patents. Forty were for refrigeration equipment, while others were for devices for theater equipment and devices pertaining to gasoline engines.

• In 1944, Jones became the first African-American to become a member of the American Society of Refrigeration Engineers.
• 1953 Merit Award, Phyllis Wheatley Auxiliary (Phillis Wheatley Club of Cleveland, Ohio), "for outstanding achievements which serve as an inspiration to youth."
• In 1977, he was posthumously inducted into the Minnesota Inventors Hall of Fame.
• In 1991, the National Medal of Technology was awarded to Joseph A. Numero and Frederick M. Jones. President George Bush presented the awards posthumously to their widows at a ceremony in the White House Rose Garden. Jones was the first African American to receive the award.
• In 1996, the Thermo King Model 'C' refrigeration unit, the world's first front-mount refrigeration unit for mobile trucks, was designated an International Mechanical Engineering Landmark by the American Society of Mechanical Engineers. Jones designed and built the prototype from junkyard salvage. The challenges were to build a structural frame and refrigerant tubing connections that would withstand the constant pounding of road vibrations.
• In 2007, Jones was inducted into the National Inventors Hall of Fame, which honored him as a "Visionary Veteran."
• In the March 2009 issue of Heavy Duty Truck magazine, editor Tom Berg dubbed Jones "The King of Cool", and wrote that his "technological breakthrough redefined the global marketplace, with cultural reverberations felt from the world's largest cities to its most isolated villages."
• In 2015, Jones' achievements were recognized by the creators of a Black heritage-themed playground located in Minneapolis. The playground features train-themed equipment with an educational plaque explaining Jones' mobile refrigeration technology.
• In 2022, several Black-owned breweries honored Jones during Black History Month. They released commemorative beers featuring the likeness of notable figures in Black history, including Jones.

Death

On February 21, 1961, Jones died of lung cancer at age 67 in Minneapolis, Minnesota, predeceasing his wife, Lucille. In an obituary in the Saturday Evening Post, it was said, "Most engineers start at the bottom of a project and work up, but Fred takes a flying leap to the top of the mountain and then backs down, cutting steps for himself and the rest of us as he goes." Jones continued filing for patents almost up until his death, receiving his last patent in February 1960.
