After starting a metallurgical company in 1967, Clad Metals founder John Ulam was awarded more than 50 US patents for various bonded metals and manufacturing processes. Within four years, John launched All-Clad Metalcrafters and the company started producing cookware. By 1981, All-Clad had become Americas leading premium cookware brand, eventually introducing a full line of stainless steel products in 1990. Today, All-Clad cookware is still manufactured according to rigorous quality standards.
