1903 Minnesota Mining and Manufacturing Co

The five founders of 3M financed the company to mine mineral for grinding wheel abrasives. Like many others in the early 1900’s, 3M’s founders incorporated first and investigated later. In the face of failure, they persevered and turned an investment into a lucrative venture. John Dwan and Henry S. Bryan both sign as officers at front of this 1903 Minnesota stock.
