Researching Joe Hewitt

His first project took place while still attending Hopatcong High School. He created the website Feff World with Douglas Palermo. From 2000 to 2003, he worked on UI programming at Netscape. Subsequently, he worked on AOL's Boxely UI project, which renders software such as AIM Triton and AOL Explorer.

He has been working on Parakey with Blake Ross. Parakey was acquired by Facebook in July 2007.

In July 2007, Hewitt led the release of the iUI user interface library which greatly simplified Safari development for Apple's iPhone. In August 2007, he wrote the iPhone-specific version of Facebook. He was responsible for creating Facebook’s iPhone app, which as of 2009 was the most downloaded iPhone app of all time. In November 2009, Hewitt ceased development on the application, citing Apple policies. In January 2009, he released the open-source library for iPhone developers Three20.

In 2011, Hewitt left Facebook.

Described as a "small, dapper man", who was "outspoken, even 'cocky'", Hewitt overcame the setback to his career during the war and made his most significant contributions afterwards, as Air Member for Personnel from 1945 to 1948. Directly responsible for the demobilisation of thousands of wartime staff and the consolidation of what was then the world's fourth largest air force into a much smaller peacetime service, he also helped modernise education and training within the RAAF. Hewitt was appointed a Commander of the Order of the British Empire in 1951, the same year he became Air Member for Supply and Equipment. Retiring from the military in 1956, he went into business and later managed his own publishing house. He wrote two books including Adversity in Success, a first-hand account of the South West Pacific air war, before his death in 1985 aged 84.
