WILLIAM RUSSEL QUINAN

Hailing from Maryland in the United States of America, this West Pointer, soldier, dynamite manufacturer, inventor, chemist and engineer came to South Africa at the turn of the century to set up the Cape Explosives Works for the De Beers Consolidated Mines. This led to the establishment of a commercial explosives factory which has played a significant part in the growth of industries requiring explosives in South Africa and countries beyond our borders.
    His knowledge of the chemistry of explosives and acids, with relevance to their behaviour and production, as well as his engineering of plant and equipment established him as a leading and outstanding explosives technologist. Many of his inventions are still in use today. With his innovative approaches to management, research and development, training and many other disciplines, he innovated and set standards that were far ahead of his times. 

 

DR JEAN DE VILLIERS

Dr Jean de Villiers, founder of the former Unit for Applied Chemistry at the CSIR, led this very successful research group for seventeen years. During this phase of his life he he received many medals and awards for his contributions to combatting terrorism. The Order of the Star of South Africa (Commander) and the South African Police Medal for Combatting Terrorism are among these. Dr de Villiers also initiated the large explosives and arms symposia previously staged, the first of these attended by 120 delegates in 1977. This was followed by a series of Rapid Physical Effects Symposia. 

On Friday 2 March 1984, while attending a Strategic Studies Symposium he died of a heart attack. He was 54 years old.

DR VERNON JOYNT

Dr Vernon Joynt received his B.Sc. And M.Sc. (Chemistry) at the University of Pretoria and in 1963 he was awarded his Ph.D. in Organic Chemistry at the University of South Africa. He also attended a large number of military courses. Much of his military work was done whilst employed by the CSIR. The group which he headed became Mechem, a member of the Armscor group in 1988, but transferred to become a Division of Denel in 1992.

As a civilian working for a civilian organisation, Dr Joynt received several military and police commendations. In 1978 he received both the commendations of the Head of the Army and the Head of the Defence Force.

In 1980 he received the Police Medal for the Prevention of Terrorism and in 1981 recognition for his services to Armscor in the field of armaments. This was for the development of the first mine protected vehicles. He was awarded the Order of the Star of South Africa (Civil), Commander in 1982, and in 1983 he was one of the three merit prize winners in the CSIR. In 1989 he was awarded the Armscor prize for the development of MEDDS, the Mechem Explosive and Drug Detection System, which combines chemical concentration of vapours with the acute sense of smell of specially trained dogs.

Dr Joynt is responsible for a large number of innovative military designs. One comprises the first operational rocket propelled anti-tank minefield line charge breaching system used by the South African forces. His teams also designed and qualified manpack and manportable line charge systems. On the vehicle side Dr Joynt designed the first wedge shaped mine protected vehicle, the Hyena. He and his team subsequently designed and initiated the production of the Hippo, Buffel, Casspir and Swerwer personnel carriers. The mine protected ambulance, Rinkhals, and a series of civilian mine protected vehicles called Ribbok and the Rooibok were also products of the unit at the CSIR under Dr Joint. The latter were used to protect South African Farmers against terrorist land-mines. A very effective mine-sweeper system for the patrol of roads were also developed. Some of the more recent lines developed by Mechem include the Mamba series of vehicles. Mine and armour protected, their use include both military and civilian applications.

Mechem, now operating as DefenceTek, is  internationally recognised for its humanitarian landmine clearing expertise, which has enabled this Division of Denel to accept various contracts which could have appeared impossible to other organisations.

WILLEM PELSER

Willem’s involvement with the explosives industry goes back as far as 1970 when he was appointed lecturer at the Technikon Pretoria. With a B.Sc degree in chemistry and mathematics obtained at the Potchefstroom University and some industrial experience as a chemist, one of his first tasks was to develop a course in explosives technology. Spending considerable time in the explosives industry and with their support, the well-known National Diploma in Explosives Technology was born, eventually followed by higher qualifications. Willem may rightly be regarded as the founder and ‘father’ of training in explosives technology in South Africa. 

During his stay at the Technikon he obtained a Masters degree in chemistry (with distinction) as well as a post-graduate Diploma in Education. As Head of the Department of Explosives Technology, he was also appointed as Director of the School of Chemical Sciences.

In 1984 he left the services of the Technikon to join the armaments industry. In 1992 he became part of the Senior Management in the newly founded Denel group. He first served with Kentron and then became MD of Advena. In 1993 he was appointed Managing Director of Naschem, but had to retire in 1996 due to ill health.

During his time with the armaments industry he completed numerous courses locally and abroad in areas like general management, advanced financial management, project management, business alliances, negotiation skills, etc. He also attended the Joint Staff Course of the SANDF where he was adjudicated as the best overall candidate.

Willem has particular interest in education and training and was involved in this field in one or other capacity for the best part of his career. After leaving the Technikon he acted as national examiner or moderator for various subjects in the field of Explosives Technology, also acting as tutor for many post graduate and post diploma students. During his years at Naschem he initiated a training project for science and mathematics teachers with poor qualifications in these subjects at the Potchefstroom University. This initiative has grown into a very successful venture which will eventually produce many more school leavers with science and mathematics as subjects.

Since 1997 Willem acted as training consultant to the Denel group surveying the industry’s need for training in explosives technology. The present series of courses is an outcome of this thoroughly executed task. They were painstakingly developed and taken through the demanding accreditation exercise through the South African Accreditation Association (SAQA). Initially presented through the Technikon SA, they now, after the merger, are hosted by the University of South Africa (UNISA). Any member of the explosices industry is now able pursue studies up to doctorate level.

Willem was also a co-founder of NIXT, member of its Advisory Forum handling its  and  responsible for training activities.

Willem presented the Jean de Villiers Commemorative Lecture at the NIXT 10th Anniversary function. The title of his paper was: Training in explosives sciences: An overview and future perspectives.

In 1996 Willem was taken ill with a heart virus and had to undergo a heart transplant. For the next ten years his time was taken up with the structuring of courses and a variety of other commitments. Towards the end of 2005 his health deteriorated considerably and on 9 February 2006 he sadly passed away at the age of 63.

Willem was truly a man who put his heart into everything he did!

BRIGADIER PINE PIENAAR

The late Brigadier Pine Pienaar started his career in the South African Defence Force in 1939 as armaments instructor at the Military College of the South African Instructional Corps, a position he held for 17 years. In the early fifties the BSA factory was founded with Brigadier Pienaar involved with the acceptance of certain equipment. During this time he was seconded to the Quartermaster General in order to gain knowledge and experience with the manufacture of armaments. This included a specialist course in the UK.

He was subsequently appointed in the technical services of the South African Defence Force. In 1962 he was appointed as SSO Proofing, which intensified his inputs with regards to the manufacture of ammunition. 

The refining of our ammunition over many decades accompanied by rigorous quality control culminated in South Africa's successful entry into the world markets, which also offered an excellent example to other disciplines in industry. In 1975 Brigadier Pienaar was appointed as Director of Explosives, a position he held until his retirement in 1979. He still remained involved with the industry by being appointed as technical advisor in Armscor's Directorate Quality . He gave many lectures at the various manufacturers of armaments on the internal and external ballistics of ammunition, fragmentation of grenades, the various types of grenades and their filling, propellants en methods of initiation.

Brigadier Pienaar always believed that ammunition constitute living tools that can be used to create a work of art, even though in destructive way. He rightfully deserve the title: Father of the South African Ammunition. His death in 1997 meant a great loss to South Africa's armaments and defence industries.

Brigadier Pienaar presented the Dr Jeanne de Villiers Commemorative Lecture at NIXT '90 in Pretoria.

CHRIS  VERMEULEN

Chris Vermeulen obtained a B Sc (Chemistry and Mathematics) in 1952 at the University of Stellenbosch. His career commences at AECI as a chemist. During the first two years he came to know the characteristics of explosives through its chemical analysis and testing, laying the foundation of his thorough knowledge of explosives.

In 1955 he was seconded as Factory Chemist to AECI’s factory in Zimbabwe where he played a major role in the commisioning of a new phosphate plant. In 1958 he returned to AECI at Somerset West, acting as the Superintendent of the explosives plant. He there handled manufacture, technical investigations and development.

Within eight years of graduation he was promoted to a Section Manager and seconded to the project to establish the manufacture of military explosives and propellants. This was during the years when the arms boycott commenced and Somchem was conceived. Founded in 1971, Somchem was managed by a team including Chris Vermeulen as Production Manager under Colffie van der Colff, the Factory Manager. 

 

He immediately established a culture of explosives discipline which is still being maintained. Safety, quality and discipline were priorities with him, and in spite of production pressures, were never relaxed. He inspired each and everybody to think, think, think before attempting anything dealing with explosives. He was a master "devil’s advocate", always acting with safety in mind. Over many years he developed close links with NOSA, SAFEX and the Inspectorate of Explosives and was held in high respect as an explosives expert on operational matters by everybody.

 

His overseas visits and contacts kept him abreast with current developments and practices. This came in good stead when he was commissioned to establish a new, modern factory at Krantzkop near Wellington where only the latest technology was employed. Production started within two years and one year later a NOSCAR was awarded for achieving the highest safety levels at this factory.

 

In 1991, after 33 years in the explosives industry, Chris retired, knowing that no serious explosion ever occurred in areas under his control.

 

This giant of the explosives industry made his outstanding contributions with great modesty and dignity. He left a heritage of a sound explosives culture and operational discipline that inspired and guided all subsequent generations to come at Somchem.

 

Chris Vermeulen received the NIXT Golden Medal Award in 2001.
