Association of Lighting Designers
However it became evident that with more designers of physical "things", discussion about the less tangible role lighting played in design became much reduced. Therefore in the early 1980's the Association of Lighting Designers was created, and once again the art and technology specific to how a stage was lit were at the forefront of its aims.
Our beginnings were largely informal. In 1961, regular meetings of nearly all the people who worked as Theatre Lighting Designers in London could happen round a single table at Rules Restaurant in Covent Garden.
In the mid-1970s membership broadened to include set and costume designers and the name was amended to the Society of British Theatre Designers, an organisation that still exists today.
