1901 - 1975 World Events

Refresh this page to see various historical events that occurred during Leonard's lifetime.

In 1901, in the year that Leonard Hart was born, the first Nobel Prizes were awarded. Chemist and engineer Alfred Nobel, who died in 1896, had provided in his will for prizes in physics, chemistry, and physiology or medicine, who have produced the most distinguished literary work of an idealist tendency, and who have contributed the most toward world peace. The winners in 1901 were: Wilhelm Conrad Röntgen for physics, Jacobus Henricus van't Hoff for chemistry, Emil Adolf von Behring for physiology or medicine, Sully Prudhomme for literature, and Jean Henry Dunant and Frédéric Passy for peace.

In 1914, he was only 13 years old when in August, the world's first red and green traffic lights were installed at the corner of East 105th Street and Euclid Avenue in Cleveland Ohio. The electric traffic light had been invented by a policeman in Salt Lake City Utah in 1912.

In 1926, by the time he was 25 years old, on November 15th, NBC was founded. It was the U.S.'s first major broadcast network. Ownership of the network was split between RCA (a majority partner at 50%), its founding corporate parent General Electric (which owned 30%), and Westinghouse (which owned the remaining 20%).

In 1938, Leonard was 37 years old when on June 25th (a Saturday) the Fair Labor Standards Act was signed into law by President Roosevelt (along with 120 other bills). The Act banned oppressive child labor, set the minimum hourly wage at 25 cents, and established the maximum workweek at 44 hours. It faced a lot of opposition and in fighting for it, Roosevelt said "Do not let any calamity-howling executive with an income of $1,000 a day, ...tell you...that a wage of $11 a week is going to have a disastrous effect on all American industry."

In 1975, in the year of Leonard Hart's passing, in January, Popular Mechanics featured the Altair 8800 on it's cover. The Altair home computer kit allowed consumers to build and program their own personal computers. Thousands were sold in the first month.
