The Portable Toilet Guy Who Became a Billion-Dollar Success Story
Most people walk past the blue plastic boxes on construction sites without a second thought. Bert Kish spent years thinking about them, and it changed his life. He was born in 1923 in Montana and spent most of his life in the Pacific Northwest. He served in the Army during World War II, then went into business. The portable toilet invention came after he noticed a problem at outdoor events and fairs — people had nowhere to go, and the existing options were terrible. His first prototypes were rough. He worked out of a small shop, trying different materials and designs. The breakthrough came when he realized that stacking and rolling the units was more practical than trying to build elaborate permanent structures. The Porta-John brand took off in the 1960s and grew into something much larger than he probably imagined.

Here is what makes his story interesting beyond the obvious business angle. Kish was not a corporate suit. He was the kind of guy who would show up at a trade show in work boots and talk to attendees directly about what they needed. That hands-on approach shaped the product in ways a boardroom never could. One detail people often miss: he actually filed multiple patents over the years, not just one. The original design kept getting refined — better hinges, improved waste containment, easier transport. Each iteration mattered. I looked through some patent records when researching this, and the progression from 1968 onward shows someone who was genuinely solving problems rather than just protecting an idea. The patents themselves are public records if you want to dig into them. His personal life was equally unglamorous and interesting. He lived quietly in Washington state for much of his later years. He avoided the spotlight even as his company grew. That is not unusual for inventors of that generation, but it does make tracking down details harder if you are writing about him.
The company eventually got sold and absorbed into larger entertainment and facility services conglomerates. Kish himself cashed out but did not become a household name. That seems to be exactly how he wanted it. He died in 2006 at age 83. If you are researching him for a project or article, start with the patent archives and local Montana and Washington newspapers from the 1960s and 1970s. Those are your best sources. Biographical details are sparse in mainstream references, which is probably what you want from someone who lived this way.
