Noel Desmond Gray (26 December 1920 – November 1999) was an Australian technician, co-founder and initial financier of the medical electronics company Telectronics Pty Ltd.[1]
Telectronics
Telectronics Pty Limited was incorporated in Sydney, Australia, in 1963[1][2] formed medical student and senior design engineer Noel Gray. Technician Geoffrey Wickham was given one share and initially designed industrial electronics. Gray introduced the pacemaker and medical electronics concepts with the experimental P3 pacemaker used in experiments in 1963.[3][4][5] The corporate name was derived from "Television and Electronic Services", operated by Noel Gray as a sole trader from 1959-1964.[1]
The company made significant contributions to pacemaker technology including the first definition of the relationship between surface area of the heart electrodes & pacing pulse characteristics, the first use of integrated circuits and the first hermetic titanium encapsulation.[1][2]
Nucleus Holdings Pty Limited, a company incorporated in 1967, became a 50% shareholder of Telectronics in January 1968. In 1975 Nucleus Holdings Pty Limited transferred it's shares in Telectronics to Nucleus Corporation Pty Limited and reduced the holding by sale of shares to a French multinational leaving a 33.33% holding by Nucleus Corporation Pty Ltd which became the publicly listed company Nucleus Limited 1980.[6] In turn Nucleus Limited was acquired by Pacific Dunlop in 1988. Legal action over the sale of faulty "J Lead" electrodes, inherited by Telectronics in acquisition of pacemaker manufacturer Cordis corporation of Miama led to the company having to settle extensive worldwide compensation claims. This led to the sale of Telectronics assets to, eventually, St Jude Medical of Minneapolis and Pacific Dunlop restructuring itself into Ansell.[citation needed]
