John F. Bishop, known to his friends as Jack, was a Beckman Instruments employee who worked on the Flow Colorimeter, among other projects. The couple in the photograph are identified as Otto and Maria Haunold.
The pair fled to the United States in the wake of the Hungarian Revolution. They applied for a marriage license to wed in Whittier, California in January 1957. Otto Haunold's connection with Beckman was not limited to a goodwill photograph; he was an inventor and over the next quarter of a century assigned several patents to Beckman.
