Cotton rope for Petromax

The Petromax lamp was developed in 1910 by Max Graetz, who also gave the brand its name, on the basis of a well-known spirit incandescent lamp. At the time, when electricity was far from being available in every household, it was a great step forward to make such a bright light available and affordable for everyone. Graetz secured the rights to the name "Petromax", which was derived from "Petroleum Maxe", as his friends and confidants affectionately called him. In the end, the lamp, in different versions, became a worldwide bestseller.
