Neville Jeffress

Neville Jeffress (29 July 1920 – 13 September 2007) was an Australian advertising executive and the founder of Media Monitors Australia, now called Isentia.

Background Jeffress was raised and educated in Sydney. In 1936 he joined the Afternoon Sun newspaper in Sydney as a clerk in the publishing department, before enrolling in the Royal Australian Air Force as a wireless operator/airgunner in 1941, where he served for five years.

The Rennie agency, which started in the late 1940s, specialised in advertising industrial and technical products, processes and services. The active partners of the Rennie agency at the time were Les Rennie, Owen Amos and Ken Baker.

The Neville Jeffress Advertising agency, including L. B. Rennie and Partners, was sold to the United States-based conglomerate, TMP Worldwide Inc in 1996.
