In 1960 David Marshall's life changed forever in the shark-infested waters of the South Pacific.
Surviving a traumatic 'man overboard' experience, and prompted by the continuous loss of life at sea, he embarked on a quest, dedicated to inventing a rescue beacon and improving maritime safety.
A tortuous, lifelong struggle followed in the face of endless difficulty, before success was eventually achieved. Battles against devious American investors, unsupportive banks and British Government bureaucracy, were just some of the hurdles he had to overcome.
Today, David Marshall's beacon has helped save thousands of lives.
This is his remarkable story.
