SC 6 - JTC 1

ISO/IEC JTC 1/SC 6
Telecommunications and Information Exchange between Systems

September 2025

Preface

As you will see, ISO/IEC JTC 1/SC 6 has a long history spanning over half a century. It was not an easy task to find old documents. Fortunately, we had an SC 6 historian, Mr. Jack Houldsworth from the UK. Since he joined SC 6 in 1966, he narrated SC 6 history until 2007, also serving as the convener of SC 6/WG 18, a nonofficial honorary WG for the social committee. After he passed away in 2008, this work was not continued until JTC 1 asked all its Sub-Committees to keep their own history for informational purposes.

Dr. Hyun-Kook KAHNG, former SC 6 Chair, collected the documents and restarted the work of writing the SC 6 history. However, in an era of rapid and revolutionary ICT technology change, he has written this focusing on the SC 6 projects carried out in each Working Group (WG). It may seem a little dry since it is mainly based on resolutions.

SC 6 Chair, Dr. Shin-Gak KANG, plans to review the details of previous SC 6 meetings and supplement the currently described history of SC 6 with more enhanced information.

The Beginning and Early History of SC 6

The first moves towards the creation of SC 6 occurred in Paris in 1962 when ISO/TC 97 set up a Special Working Group (WGF) to study Data Link Control Procedures and Modem Interfaces under Alan Stillman from the USA. Werner Hofmann (from Germany) and Lionel Durand (from France) attended this meeting and remained with SC 6 for many years. Jack Wheeler from the USA, another of our long-standing members, attended the first WGF meeting in Geneva in 1963.

The formal establishment of SC 6 came in New York City in 1964 when TC 97 formed several sub-committees. The author of the early history, Mr. Jack Houldsworth from the UK, joined at the third meeting of SC 6 in Stockholm in 1966 and attended all subsequent meetings.

Alan Stillman was elected as the first Chairman and held this position until his untimely death in 1973. He was succeeded by Mario Ballabeni of Italy for one year, and then Ed Lohse held the position for over 12 years, our longest-serving Chairman. Hal Folts took over in 1988, followed by Jack Wheeler in 1993, and Jim Carlo in 1997. The secretariat was held by the USA from the first meeting until 2001, when it was handed over to Republic of Korea under Secretary Jooran Lee and a new Chairman, Professor Joon Nyun Kim.

The Origin of Working Group 18 (WG 18) – The Social Committee

In 1971, a tradition began where each national delegation would submit a light-hearted contribution to the Special Working Group, which “convenes” after the SC 6 dinner. This Group was dubbed “WG 18” by Chairman Ed Lohse during the SC 6 meeting in Washington in 1984, and Jack Houldsworth was designated as its “Convenor.” It was Jack’s 18th year in SC 6. However, this tradition was disbanded after Mr. Houldsworth retired.
