I have a large stack of strobe picts from 1952 around here somewhere. Along with other junk.
Back then a fellow $127/month Great Lakes sailor and myself wanted to get strobe flash units. Having just blown my savings on a Speed Graphic we got creative. We called Life Magazine and asked where they got their studio units from and they directed us to Strobo Reasearch in Millwaukee. Next liberty we headed off to BeerTown and looked up SR. We found them, they looked open so we went in and introduced ourselves. They were setting up shots of a baseball breaking a window and asked us if we wanted to stay and help. Spent the rest of the day with them and left with schematics and drawings of their upcoming "Portable" model.
We made up a pair of units in the Base Hobby Shop with parts from Chicago's surplus market and Allied Radio. The four main Capacitors were surplus Sonar ones rated at 12mF @ 2500V charged to 2000V with an oscilloscope transformer. That's 96 wattseconds! The finished units were about the size of a breadbox and weighed in at 15 pounds, the flash head was a coffee can with a cut down auto headlight reflector, and LOTS of insulation. Total cost was around $60 including the GE flash tube. I used mine for about ten years until the caps finaly died. The SR guys were really impressed with what we did and gave us a lot of tips and practice time in their lab. Lots of bits of fruit and veggies, broken glass and Cordite fumes. Ah, the joys of my mis-spent youth...
One of the best shots we helped with was a bullet leaving the barrel of a .38 S&W halfway to my buddy's head, a double exposure of course.
The company sold out to Graflex after we left Great Lakes and later became part of Honeywell.
