Beames' engineering business was originally located in Clements St. Five Dock, and moved to the Blue Mountains following World War II. Despite being highly regarded in the scientific engineering and astronomical community, the story of Ken Beames and his work remains largely untold. Following his death in 1989 (aged 89) his estate passed into the hands of a trust. With few funds available the trust, the Linden Observatory Trust has struggled to maintain the site with the help of volunteers and members of the amateur astronomical community. Ken Beames work and history is unique and worthy of research and conservation. The long term viability of the site is unknown and the collection and its integrity is at risk without conservation measures. The site is still in use by amateur astronomers in keeping with Ken Beames' wishes that it be used for amateur astronomy and education; on two occasions supernova have been discovered by observers at Linden. A significant assessment of Beames' sketches and engineering drawings has been made by Mr. Julian Holland in 2008. This work is being funded by a Community Heritage Grant obtained by the observatory trustees. Heritage listing The Linden Observatory is State heritage significance for its historic values as a rare and representative example of a twentieth century amateur astronomy observatory complex including telescopes and other instruments, dome observatory building and the complex of workshops and machinery used to make all the instrumentation and supporting infrastructure. The observatory is evidence of the significant technical and innovative abilities of its creator Ken Beames. He was one of the very few instrument makers working in Australia during the early and mid 20th century when most professional and amateur instruments were imported from Europe of America. Beames' work as an astronomy instrument maker and optics maker was highly regarded by his peers at the time and is still acknowledged as a major contribution to the history and development of astronomy in NSW. It is also tangible evidence of the continuance of the strong collaborative tradition between professional and amateur astronomers through the decades of the twentieth century. Ken Beames' contribution to the history and development of NSW is also marked by his input to munitions production during WWII where his skills at manufacturing optical components was sought after by the government faced with a dearth of ability in that area.
