Adele De Berri was a 24-year-old young woman and the inventor of the Silver Screen. At a time when businesswomen were rare and couldn't vote, Adele established Da-Lite – a business that would survive the Great Depression, World Wars and multiple recessions. Over 100 years later, with an in-house team of chemists, we remain committed to improving our surface formulations to ensure the best surface for today and future projection technology.
