Captain Stanley R. Mullard had initially developed electron tubes for the Admiralty and then became Managing Director of Z Electric Lamp Co. In 1920 he founded Mullard Radio Valve Co.

In 1928 Mullard launched the first pentode based on Philips patents on the British market.
Mullard u. a. in Mitcham (1929) and Blackburn (late 1930s). Mullard later made semiconductors in Southampton and Stockport near Manchester . The first products were germanium - transistors (OC50, OC51, top transistors , later OC70 and OC80 in the glass case), then integrated circuits .
At the end of the 1980s, Philips combined the semiconductor activities in the Philips Semiconductors division (today NXP Semiconductors ), the (formerly regional) brands such as Valvo , Signetics and Mullard were no longer used.
The IC factory in Southampton was closed in 2011 and the NXP factory in Manchester is now producing power semiconductors.
