Many years ago, in Secaucus, New Jersey, a young man, Fred Danzerly, an amateur skin diver, was working on a light, a bright light, that he could use, under water on his dives, to illuminate the ocean floor beneath him.
He had tried many different bulbs and systems. He wanted it self contained so that he would not have to worry about staying in contact with the boat above him, and not be encumbered with a lot of lines.
He worked for a number of years, in his spare time on his light. Fred worked for the Secaucus Power Company, and it was this association with lights and electricity that got him interested in the project in the first place.
He finally felt he had it perfected, and was ready to give it a test.
It was determined that Rosarita Beach, Mexico, offered the deepest, darkest water, and also was an area where many highly qualified divers could be found.
Fred, with his light carefully encased in a foam case, flew to San Diego, rented a van, and proceeded to drive the rest of the way to Rosarita Beach.
Upon arrival, he rented a room at the Casa Mananna Hotel, and proceeded to look around for a boat to charter, and a diver to try out his light.
He was referred to a diver, Jose Martinez, Fred talked with him, they came to terms on his salary, and Fred instructed Jose on exactly what he expected to accomplish during the test.
They left on the chartered boat early the next morning, Fred, Jose, and a crew of three. It took them over an hour to reach the area in the ocean that offered all of the conditions necessary to accomplish the test.
All was ready, Jose had his diving suit on, Fred's new deep sea light, all was ready on the deck. The equipment was ready to insure that the life sustaining oxygen would be supplied to Jose on his descent to the dark ocean bottom.
Jose went over the side, it took over 30 minutes for him to reach the desired depth.
A very anxious Fred spoke to Jose on their communication system, "Is the darkness intense enough,"?
Jose said, "Yes."
He then told him to "Turn on the Light."
After an anxious few moments, Fred could wait no longer, he took the microphone in hand, hesitated a moment, and said, "Jose, can you see by the Danzerly light?"
