Quaker History

Quaker Window Products was founded in 1949 by Marge (1919-2013) & Harold (1914-1994) Knoll, who established a business philosophy in the beginning years that has stood the test of time. The philosophy includes a dedication to detailed workmanship and responsive service.

1949 Quaker Shade Co. was started by Harold & Marge Knoll in St. Louis. Later that year, it relocated to Marge’s hometown of Freeburg, Missouri.
1952 By the end of 1952, Quaker had 11 employees on the payroll.
1954 The company began making aluminum storm windows and storm doors.
1957 Quaker had grown to 65 employees. Also, an article in Building Specialties magazine stated Marge Knoll was “probably the only woman general manager of a window company in the country.”
1961 The Knoll’s saw a huge market opportunity, and introduced Quaker’s first aluminum  replacement windows.
1962 LIFE Magazine referred to Quaker as a nationally-recognized brand for quality windows.

2009 The company’s 60th anniversary was celebrated.
2012 Quaker expanded once more, and again, it was their biggest building to date. Mike Knoll’s foresight became a state-of-the-art powder coat paint facility. At 110,000 sq. ft., it was affably referred to as “Mike’s Monster”.  Kevin Blansett named CEO in December.

2018 Quaker’s south campus saw another 185,000 sq. ft. facility open in January. It would house all wood window and door manufacturing.  Employee count overall had now reached more than 950. In November, a ground-breaking ceremony was held in Eldon, MO – site for the next Quaker expansion. Work on a new 200,000 sq. ft. building had begun by the end of the year.
2019 In January, Quaker began full production of a new, trailblazing window series called OptiCore™, the most innovative product ever developed by the company. The patented window earned rave reviews from industry experts and put Quaker at the forefront of the luxury home market. As well it became a force in the commercial window industry. Later that summer, for the first time in its history, Quaker had more than 1,000 employees.
2020 Phase 1 of Quaker’s Eldon expansion project was completed in May — a 200,000 sq. ft. manufacturing and office building. Approximately 200 people are expected to work there once the facility is at full capacity.
