Union Branch , Natural History Museum

The Natural History Museum Staff Association was inaugurated at a general meeting on 18 October 1918, with Mr Fagan, the Museum Secretary, as the first Chairman.The Association was open to all officers and assistants in the Museum, and was a grade group of the Society of Civil Servants. It was concerned with pay and conditions of its members, the status of the Museum, and organised regular scientific reunions and less formal tea parties. The Association was affiliated to the First Division Association in 1945, transferring its affiliation to the Institute of Professional Civil Servants in 1950, at which point it was renamed the British Museum (Natural History) Scientific Officers Association, following the name change of the assistant class.

The Museum's attendants set up the Natural History Museum Clerks Association in 1919, and became affiliated to the Civil Service Federation in 1920. In 1921 they became the Natural History Museum Branch of the Civil Service Clerical Association, and transferred to the Institute of Professional Civil Servants in 1946. In 1950 it was renamed the British Museum (Natural History) Experimental Officers Association, following the name change of the attendant class. The attendants had had a number of disputes with management before the formation of the branch, documented in the petitions and other papers in items 14-21.
