The first studies of lightning and the development of lightning protection methods began over 250 years ago. Despite this, modern lightning protection still leaves many questions open. We asked Eduard Meerovich Bazelyan to tell about the history of lightning protection and some interesting facts from the work of the Laboratory of mathematical modelling of electrical processes (ENIN to the name of Krzhizhanowsky). The laboratory, now headed by Professor E.M. Bazelyan, was formed in 1936 and became a place of unique discoveries in physics of lightning and discharges, often accompanied by world records.
