Eugene Walter Klein

Founder

Eugene Walter Klein is the visionary founder of Parkway-Kew Corporation, establishing the company in 1952 after identifying an innovative solution to a pressing industrial challenge. As a welding supply salesman, Eugene was approached by a valued customer seeking help repairing worn machine parts and improving their wear resistance. Drawing on his expertise, he recommended a specialized hardfacing wear-resistant weld alloy, proved the concept by welding the first test piece in his own garage, and secured the company's landmark first order to rebuild 100 wire drawing blocks. His entrepreneurial spirit and deep technical knowledge laid the foundation for what would become the world leader in hardsurfaced wire drawing blocks and capstans, a legacy that has endured for over 70 years.
