The R.H.P. brand, intellectual property rights and company assets were absorbed into the Japanese NSK Ltd. bearing company in early 1990 trading as NSK-RHP Ltd. at its UK base in Newark on Trent with the historic R.H.P. name finally disappearing in 2001. Most of the former Hoffman New Street factory was demolished during the summer of 1990 and the site is now occupied by the sprawling Rivermead Campus of the Anglia Ruskin University. The only connection to the company name in Chelmsford today is the RHP Bowls club located on part of the old Hoffmans Social Club site at Canterbury Way and Hoffmans Way at the corner of the old factory site at New Street and Rectory Lane. The Waterhouse Lane–based company began in the early 1940s as a part of the Marconi group, manufacturing magnetrons for defence radar systems. The company was first registered as a separate company in Chelmsford, Essex in 1947 under Serge Aisenstein. Its initial name was the Phoenix Dynamo Co Ltd, though it immediately changed its name to English Electric Valve Company Ltd. In 1959 Bob Coulson established Traveling-wave tube and Microwave tube sections and they were producing ceramic hydrogen thyratrons as well. By this time EEV was the largest hi-tech manufacturing company in the UK. A year later they won an EMMY award for outstanding contribution to Electronics Technology in developing the 4½" orthicon tube. In 1961 they acquired Associated Electrical Industries Valve business based in Lincoln. Sir Charles Oatley was a director of the company from 1966 to 1985. In 1962, EEV opened its first office in America in Buffalo, NY. In the 1970s EEV collaborated with QinetiQ in the development of the pyroelectric vidicon, the first thermal imaging detector. The company has received 13 Queen's Awards for Technology in its history, most recently in 2006 for low light imaging devices and in 2004 for thyratrons for cancer radiotherapy treatment. Also, in 1972, they opened an office in Paris, France and in 1977 they opened another office in New York but this time in Elmsford. Keith Attwood, e2v's CEO joined in 1999, as MD of EEV, after a short period as Marconi Applied technologies, the company was renamed to e2v technologies in 2002 as part of a management buy out supported by 3i following the collapse of the Marconi group. Following further growth under 3i, in 2004 the company floated on the London Stock Exchange.
