Fulmer grew steadily so that by 1960 there were about 100 staff. Individual research investigators were often recruited to work on specific projects as contracts were obtained.  Each recruit was also expected to develop proposals for work in his or her areas of expertise, whether or not these fitted into Fulmers existing pattern of work.  This system resulted in a progressive evolution and wide diversification of Fulmers skills base. This was a strength in that faced with a materials problem Fulmer could usually help the client with new perspectives.
