The museum moved forward when Ramona Sahm donated one million dollars. Educational outreach programs began in 2000 as plans for the museum building were being developed. The name 'lux' was chosen because it means light in Latin. Interestingly, the site chosen for the museum was once called Lux Canyon, named after a family who lived in the area at the turn of the 19th century. The museum opened in 2007 and the educational pavilion was added in 2014.
