1977 | J. Otto Crocker
Crocker is synonymous with world-recognized official timing of speed events.
In the late 1930s Otto developed the Selenium Metal Light Beam Sensitive Timing Equipment which was used for decades. Crocker speed equipment was used at over 2000 world speed events in all categories, with accuracy up to .001 second. The equipment Otto developed and constantly improved over the years was not restricted to timing powerboats; the Crocker Timing System could record anything with unquestionable results.
Many felt his advancements were as great a step forward from manually operated stopwatches as Thomas Edison's electric light was over the kerosene lamp.
