John was born near Manchester but had university education at the Universities and London (King's College). After gaining in chemistry and completing a post-doctoral fellowship at Florida State University, Department of Chemistry at Wits University. During his time department, he became a full Professor, was President of the Chemical Institute (1988-90) and was Chairman of the IUPAC Committee on Teaching of Chemistry (1996-2001). He joined colleagues to create the RADMASTE Centre in 1991 and grown to about 20 staff. As one of the creators of the microscience system he helped establish the UNESCO-IUPAC Global Programme Microscience, which has ultimately resulted in the creation other UNESCO-associated Centres for Microscience Experiments. John is currently the Honorary Director of the Centre.

Joseph was born in Rwanda and studied chemistry at the National University of Rwanda. Subsequently he obtained his PhD at the University of Nairobi. Joseph speaks English, French and Kinyrwanda fluently and has an extensive knowledge of science education in sub-Saharan Africa, especially Francophone countries. He has conducted microscience workshops in several countries in Africa.

Mpunki was born near Rustenburg and studied chemistry at the University of North West. After some years teaching primary school teachers at a College of Education she furthered her studies at Wits University, completing first a BScHonours and then an MSc in science education. She has been the principal developer of the primary microscience kit and worksheets and has managed a number of projects implementing microscience in primary schools. She has presented some of her work at local and international conferences. She speaks English, Tswana and Afrikaans.

Bina was born near Mumbai, but grew up in Johannesburg and studied at Wits University for a BSc in chemistry. After working in Zimbabwe for some time she returned to Wits to complete a BScHonours degree in science education and to join the staff of the RADMASTE Centre. She has worked on the development of air and water experiments to accompany a DIDAC module and participated in the preparation of video material showing the classroom implementation of microchemistry and microelectricity. She speaks English, Gujrati and Hindi.

Christopher was born in Boksburg and studied at Wits University for firstly a BScHonours and secondly, an MSc in science education. He has participated in teacher training and the development of a new organic chemistry kit and suite of experiments. He speaks English, Zulu and Afrikaans.

Beverly was born in Johannesburg and studied chemistry and medical biochemistry at Wits University. After completing her BSc she joined RADMASTE and was one of the initial team of people that developed the microscience concept - starting with the Basic Microchemistry kit. She was the obvious model for the videotape demonstrating several microchemistry experiments, which has now been distributed widely in several languages. She has been instrumental in preparing the full range of microscience worksheets, including her current assignment to make these available on the internet. She has managed a number of projects which include the implementation of microscience and is fluent in English and Afrikaans.

Maria was born in Athens and subsequently studied at the University of Patras for an MSc in physics. After extensive teaching experience teaching in South Africa, she joined RADMASTE and undertook the development of the microelectricity kit and worksheets. This she later extended to include electromagnetism experiments. She has extensive experience of teacher training using these kits within South Africa. She is fluent in English and Greek and also communicates in French and Italian.
