Bob Switzer
Edit ProfileEducation
In 1932, he received a scholarship from the Scaife Scholarship Foundation of Oakland, California, so he attended the College of Chemistry at the University of California, Berkeley, in hopes of becoming a physician.
Career
The brothers founded the Day-Glo Color Corporation in 1946 to develop and manufacture fluorescent paints, pigments and other products. During the summer of 1933, while working to unload tomatoes from a freight car at a H. J. Heinz Company laboratory in Berkeley, California, Bob fell and suffered several serious injuries, including a skull fracture and severed optic nerve. Doctors told him to stay in a dark room until he recovered his eyesight, a period which lasted several months.
While convalescing from his injuries, Bob and Joseph searched for fluorescent materials, which Joseph had read about and wished to use in his amateur magic shows.
The brothers inspected various products from their father"s pharmacy, using a black light to identify fluorescent compounds. After Bob"s recovery, the brothers continued to experiment with these, mixing them with shellac and eventually succeeding in producing the first black light fluorescent paints.
They founded the Fluor-South-Art Company in 1934 to develop and market their products for advertising displays. The brothers moved their company to Cleveland, Ohio, to partner with Continental Lithograph, a subsidiary of Warner Brothers Pictures, that specialized in movie posters and advertisements.
They developed and tested new applications for their fluorescent paints, including lithography, make-up, and fabric dyes.
In 1938, Bob invented Zyglo and Magnaglo, two nondestructive testing processes that use fluorescent dyes to identify defects in machined parts. The dyes penetrate small defects and are seen when inspecting the parts under black light. During World World War II, the company developed daylight fluorescent pigments, which are highly visible in daylight.
Bob produced the first piece of high-visibility clothing by dying his wife"s wedding dress.
Personal life and legacy
The couple had three children. Bob died in 1997 at his home in Shaker Heights, Ohio from complications from Parkinson"s disease.
He was 83 years old
In 2009, "The Day-Glo Brothers," a children"s book about Bob and Joseph Switzer"s invention of fluorescent materials, was published by author Chris Barton and illustrator Tony Persiani.
