Refresh this page to see various historical events that occurred during Margaret's lifetime.
In 1911, in the year that Margaret Wingrave was born, British physicist Ernest Rutherford (born in New Zealand), along with German physicist Hans Geiger, discovered the structure of an atom. He found that atoms had nuclei (a nucleus) and were circled by electrons, much as planets orbit the sun.
In 1929, she was 18 years old when on October 29th (Black Tuesday), the stock market crashed in the United States. Billions of dollars were lost and some investors committed suicide as a result, having lost their fortunes. This ushered in the 12 year, worldwide Great Depression.
In 1942, when she was 31 years old, due to World War II, automobile production in the United States was stopped on February 1st. A tire rationing program had begun the month before. Detroit - the main hub of car manufacturing - was ordered to free up assembly lines for military production. The president of the Automobile Manufacturers Association said “The automotive industry is in this war all the way". Some dealerships had to close and others expanded their repair shops. The used car market boomed (as did a black market in used cars).
In 1969, when she was 58 years old, one hundred countries, along with the United States and the Soviet Union signed the nuclear nonproliferation treaty (NPT). It called for stopping the spread of nuclear weapons, the peaceful use of nuclear energy, and the goal of nuclear disarmament.
In 1982, in the year of Margaret Wingrave's passing, on September 14th, Princess Grace of Monaco (American actress Grace Kelly), 52, died of injuries when her car plunged off a mountain road. Her 17 year old daughter, Stephanie, was also in the car and suffered serious injuries but recovered. It's believed that the accident was caused when Princess Grace, who was driving, had a mild stroke.
