Encyclopaedia of Historical Metrology, Weights, and Measures

Jan Gyllenbok was born in Lund, Sweden (1963), and graduated in 1990 with a B.Sc. in Computer Science from Lund University. Gyllenbok has over 30 years of experience of leading organizations, management teams, boards and task forces. He has been a board member and chairman of a wide range of non-profit organizations, and board member of both private and state companies. He has in recent years produced a diversity of specialist books and articles, mainly in technology and management. His interest in metrology began in his early teens, when he came across an article about various ancient measurement systems in a reference book. As the great importance of these measurement systems in different cultures through the millennia became obvious to him, he began to compare and compile information about different systems of measurement. This demanding project, which spanned over forty years, is reported in the three volumes of “Encyclopaedia of Historical Metrology, Weights, and Measures.”
