Welcome to the cave, Governor Parson!

Missouri Governor Mike Parson toured Brunson’s unique underground factory in Kansas City, Missouri on Tuesday, October 22nd. Founded in 1927 in downtown Kansas City by inventor A. N. Brunson, the employee-owned company is now represented by third-generation leader Deighton Brunson. Deighton expressed his appreciation to the governor for state programs that have helped support valuable training of Brunson employees.

Although underground facilities are now commonly found in the limestone outcroppings that surround Kansas City, Brunson founder A. N. Brunson was the first to create a permanent underground factory in this area almost 60 years ago.

As A.N. Brunson began manufacturing precision instruments for the post-war aerospace industry, the company’s downtown facility—with buses and streetcars rumbling nearby—created a difficult environment for precision manufacturing.

“I got the idea that if there was a solid place we could be fine,” said Mr. Brunson at the time. The ambitious excavation of the cave was met with skepticism from the banking and business communities, where the project was called, derisively, “Brunson’s Folly.”

Undaunted, Mr. Brunson and his brother excavated over 140,000 tons of limestone, carving out the underground factory over a 5-year period before the company moved permanently to the vast complex in 1960.

Brunson Instrument is an employee-owned company. Brunson’s more than 70 employees participate in an Employee Stock Ownership Plan (ESOP), an employee benefit plan that gives workers ownership interest in the company.
