History
EVVA (Erfindungs-Versuchs-Verwertungs-Anstalt) (Invention, Experimentation and Application Institute) was founded in 1919.[1] It wasn't until 1937 that they received their first lock patent. In 1973, Nikolaus Bujas took over the company and invested in machinery. Bujas also established an in-house research and development department in 1974.
