In the summer of 1874, Charles Jeremiah Smith started by establishing a small "hardware expertise" business in Milwaukee, Wisconsin. CJ Smith could not have imagined that this venture would grow that much and become a global manufacturer with more than 16.000 employees. CJ Smith was aware of the importance of dealing with customers, solving their problems, and helping them “find a better way” and believed in honesty and honesty.

The business that CJ Smith founded grew rapidly, becoming one of the world's largest manufacturers of metal parts for strollers and bicycles. Arthur Oliver Smith and two other brothers took part in the business of their father. A. O. Smith and his brothers shared their father's belief in technology and innovation. In 1899, in the early days of the automobile revolution, A. O. Smith developed a new light steel car skids. In a few years, Cadillac sold these skids to major automobile manufacturers. Lloyd Raymond, son of A. O. Smith, took over the family business, expanded the automotive business and introduced the world's first automatic skid production line, Mechanical Marvel, in 1921. Ray Smith and his engineers also contributed greatly to the oil and natural gas industries by developing a wide range of steel products for the oil refinery, including pressure vessels and large diameter steel pipes.

Ray Smith built an engineering organization unmatched at the time. Among the many technologies, company engineers investigated was the process of fusing glass to steel. This led to new products including glass-lined beer kegs, large glass-lined brewery tanks and, in 1936, the process for glass lining a residential water heater tank. Glass-lined water heaters quickly became the standard of the industry and remains so to this day. New businesses, including electric motors, fiberglass pipe, the innovative Harvestore® structure, and others all were established during this period.

As the company grew, it began to look outside of the United States for more opportunities. It expanded into Canada and Europe, opening small water heater operations to serve those markets. More recently, it became one of the first U. S. water heater manufacturers to enter the Chinese market. A. O. Smith employed a familiar formula in China, using its engineering expertise to develop products uniquely suited to Chinese consumers.

A. O. Smith has developed a workplace environment with integrity, mutual respect and dignity, bringing together its values ​​in every country where it started its operations. A few years later, the company entered India and became the first U. S. kettle company to serve the Indian market. Today, A. O. Smith Corporation is a global water technology company that produces residential and commercial water heaters and boilers and water treatment equipment.

Since 2013, A. O. Smith Turkey has adopted the principle of superior quality and advanced technology in the field of water treatment, while also offering a high level of technical support.
