Sad news this long holiday weekend for a car wash giant and his family. Edward Dahm, the cofounder of Mike’s Car Wash, a chain with 21 location sin three states, has died following a crash with a charter bus. The business mogul was 86.

According to the Cincinnati Enquirer, Edward Dahm started the business with his brother Joe Dahm in their home state of Indiana back in 1950. Soon the chain grew to include locations in Ohio and would be based in Cincinnati. When the brothers started the wash more than 60 years ago, it was the first automated car wash in the entire state of Indiana. It was called Mike’s Minit Man.

Many changes have taken place within the company over the years. In 1993, Edward Dahm and his brother Joe Dahm passed their business onto their children In 2014, about half of the locations spun off into a new business venture called Crew Carwash.

Edward Dahm died in a crash when his SUV struck a charter bus. No one else was killed but 16 of the charter bus passengers were injured. So far, crash investigations have not revealed what went wrong to cause the collision.

“Our entire organization wishes to extend to Ed’s family our deepest sympathy and gratitude. His faith and many friendships in the community were his driving force and he has left his mark on so many people who are better for having known him. Rest in peace, Uncle Ed,” said current company president Mike Dahm.
