Notable work

He was born in 1849 in Chișinău (Russian: Кишинёв) in the Russian Empire, now the capital of Moldova. After graduating from the Saint Petersburg Polytechnical Institute, he continued his education in Paris, where he studied chemistry.

Returning to Russia, Loran became a teacher in a school in Baku, which was the main center of the Russian oil industry at that time. Impressed by the terrible and hardly extinguishable oil fires that he had seen there, Loran tried to find such a liquid substance that could deal effectively with the problem. So he invented fire fighting foam, which was successfully tested in several experiments in 1902-1903.[1] In 1904 Loran patented his invention, and developed the first foam extinguisher the same year.[2]

Subsequently, he founded a company called Eurica, based in Saint Petersburg, and started to sell his fire extinguishers under that brand.

Modern usage of fire fighting foam.
