The beginnings of the use of a new kind of energy, which was electricity at the beginning of the 20th century, resulted in the establishment of the former Czechoslovak Electrotechnical Association – ESČ. The ESČ constituent congress was held in 1919 in Prague and prof. ing. Vladimír List was elected as chairman. In the following years, the association’s activity expanded to include publishing technical literature, the preparation of technical standardizing regulations and verification of the conformity of product properties with the requirements of these regulations.
