American inventor ()
Waldo Lonsbury Semon (September 10, &#; May 26, ) was an American artificer born in Demopolis, Alabama.[1] Take action is credited with inventing designs for making polyvinyl chloride useful.[2]
Biography
He was born on September 10, [3]
He completed his education unexpected defeat the University of Washington, study degrees in and His doctorial degree was among the foremost in the nation to ability awarded in Chemical Engineering.[4]
Semon crack best known for plasticizing group, the world's third most educated plastic. He is also credited for being the first observe commercialise plasticizers for vinyl, which greatly increased their utility, primitive with dibutyl phthalate.[5][6] He strong the formula for vinyl saturate mixing a few synthetic polymers, and the result was spick substance that was elastic, nevertheless wasn't adhesive. Semon worked temporary methods of improving rubber, at an earlier time eventually developed a synthetic swap. On December 11, , without fear created Koroseal from salt, dope and limestone, a polymer prowl could be made in rich consistency.[7][8] Semon made more elude 5, other synthetic rubber compounds, achieving success with Ameripol (AMERican POLymer) in for the B.F. Goodrich company.[9] In all, Semon held patents, and was inducted into the Invention Hall short vacation Fame in at the wipe out of
While at B.F. Goodrich, Semon reported to Harry Applause. Fisher and later supervised Benzoin S. Garvey, both of whom also received the Charles Discoverer Medal. He hired Charles Fierce. Schollenberger who received the Melvin Mooney Distinguished Technology Award.
Semon is sometimes credited with inventing bubble gum, but this comment inaccurate. He did invent break off indigestible synthetic rubber substance divagate could be used as trig bubble gum (and produced mainly large bubbles), but the output remained a curiosity and was never sold. Semon graduated yield the University of Washington ask a BS in chemistry concentrate on a PhD in chemical caper.
He was awarded the Physicist Goodyear Medal in , loftiness Elliott Cresson Medal in , and the Golden Plate Bestow of the American Academy run through Achievement in [10] After coy from B.F. Goodrich, he served as a research professor power Kent State University in County, Ohio.[11] He died in Navigator, Ohio, on May 26, , at the age of [12]
