Happy 114th Birthday to Waldo Semon, Father of Vinyl

Yesterday, September 10, marked the 114th birthday of a man who helped introduce more people to music in the 20th Century than perhaps any other person despite never picking up an instrument or plugging in a microphone. Unless you're a serious chemistry geek, you've probably never heard of Waldo Lonsbury Semon, but you've almost certainly enjoyed the fruits of his labor. Semon is the inventor of the ultra-versatile chemical compound polyvinyl chloride, more commonly referred to among audiophiles as vinyl.

At least, he's the inventor of the elastic, durable version of vinyl that's now used to make just about everything. When Semon first started experimenting with synthetic rubbers back in 1926, polyvinyl chloride (PVC) existed already, but it was considered useless. Fresh off earning his PhD at the University of Washington, Semon went to work for BFGoodrich developing a new kind adhesive rubber that could be used to coat metal.

Semon's early efforts using reclaimed crude rubber were a failure, so he moved on to synthetic compounds including PVC, which was basically considered interesting trash back then. Because this early vinyl was stiff and brittle at room temperature, Semon heated it in a solvent with a high boiling point. The resulting jelly was elastic after cooling, and the chemist quickly realized he was onto something.

Soon, he perfected a process to plasticize the polymer. Though he never did figure out how to make it adhesive, he'd created a lightweight, durable plastic that could be molded into almost any shape imaginable. The first applications for his invention included shoe soles and wire coatings, and as World War II stretched rubber supplies to their limit, vinyl took off.

The first records made from vinyl appeared in early '30s, but they didn't sell very well. The standard format for records at the time was 78 rpm discs made from a shellac-based material, and no one was in a hurry to replace their expensive, vinyl-destroying turntables.

Vinyl did offer some significant advantages over shellac, however. Namely, it was lighter and more durable, not to mention cheaper to produce: PVC could essentially be created from seawater and petroleum.

After the war, new lightweight pickups and hard, durable styli in turntables made vinyl a practical commercial choice for records at last. Shellac records managed to stick around until the 78 format died out in the late '50s. By that time, competing record formats were mostly standardized into the now-familiar 12-inch LPs and 7-inch 45s.

So began the Golden Age of Vinyl, just in time for the birth of rock and roll. Almost overnight, black discs were spinning in juke boxes and bedrooms all over America and beyond.

There is a difference is sound quality.  Vinyl is better.  Guess you'll not be in Austin the last weekend of October for "the world's largest record sale"?  Let me know what you need and I'll see if I can find it for you :-)
