Humble beginnings

The Entrepreneurial Journey of Morris Lefton and the Birth of Metal Exchange.

Entering the scrap business.

Our Founder Morris Lefton’s entrepreneurial journey began in East St. Louis in the 1940s after a tough childhood marked by his father's departure and time in a children's home. Rebellious and uninterested in school, Morris dropped out and entered the scrap business, mentored by his Uncle at Lefton Iron & Metal Company.

Launching his first company.

Morris flourished in the scrap business under the mentorship of his uncle, eventually launching his own company focused on aluminum dross processing. He built the business into a major success and later sold it to a publicly traded company, where he became president of their metals division.

The founding of Metal Exchange.

After spending over five years in the corporate world, Morris' entrepreneurial spirit never waned. He struck a deal to buy back his company, but on the closing day, the new owners reneged. Frustrated but undeterred, Morris walked out and, on that very day, founded Metal Exchange. It was the beginning of a bold new chapter, driven by his determination to take control of his destiny once again.

From humble beginnings to global leadership.

Metal Exchange was founded around the dining room table of Morris Lefton's home, with his partner Howard “Curly” Estabrook and three close friends and confidants as the original employees. Morris’ three children created banners and posters with supportive messages for their father and his team. From these humble beginnings, Metal Exchange became a global leader in the aluminum industry, and as Morris’ portfolio of businesses grew, MX Holdings was established to be the holding company to help manage the enterprise.
