1940 The daring man with his photographic box: this is how the JOKE® success story actually began. For a young man who made the idea of building cameras out of old cigar boxes a reality and which also worked fantastically into the bargain is set to have a remarkable career. The man was called Robert Kettenbaum, studied electronic engineering and ventured into self-employment with a repair business. This was the foundation of JOKE®: for half a century long, the Cologne electrical dealer Josef Joisten was part of things as cofounder and partner. The abbreviated company name well known to this day emerged from the initial letters of the company’s founders’ names. Kettenbaum constantly continued to tinker on, developed and built welding apparatus (including quality control in the yard by master Lange, see large picture), thereby laying the foundation for the JOKE® renown in the area of welding technology well known today transnationally. However, even development of the most modern welding apparatus was not enough for the creative action man. Consequently, Kettenbaum additionally sold and marketed the revolutionary VIKA square drill, which performed the “miracle” in the trade of drilling square and even hexagonal holes. He has unfortunately never revealed just how many bets he won in doing so. Finally, the commitment grew to serve tool manufacturing companies and above all mould building with innovative solutions and countless accessories. With great attention to detail, the company devoted itself to this sector and offered an ever wider and more perfect product range: diamond points, small grinding bobs, knurling milling devices for precision work, new diamond compounds, rapid frequency milling and grinding spindles and air-driven small turbines for carbide metal cutters. It was the hour of birth of the JOKE® competence in surfaces. The founder of JOKE®, Robert Kettenbaum
