Lee de forest luccile sheardown

Lee de Forest had four wives. The first of these, in 1906, was Lucille Sheardown, a marriage that was not consummated and ended in divorce that same year. The second, in 1907, was Nora Blatch, who bore him a child, but Nora was a liberated woman with an engineering background. After a few years she realized that she did not want to live in the shadow of de Forest, and by 1911 they were divorced. By 1912, de Forest had remarried, this time to singer Mary Mayo. By 1930, de Forest had married his fourth and final wife, the silent film actress Marie Mosquini.

The third time may or may not be the charm. This is Mary Mayo, Lee's 3rd wife, and they remained together and happy for nearly 15 years and together had two children, one of whom died at birth.

Happiness to de Forest was his New York home which he called Riverlure. On the banks of the Hudson, he was forced to sell it to pay his court debts.

Biography:

Inventor; radio pioneer. Born– August 26, 1873, Council Bluffs, Iowa. Parents– Henry Swift and Anna Margaret (Robbins) DeForest. Moved to Talladega, Alabama, at the age of six, when his father became president of Talladega College.  Married– Lucille Sheardown, 1906; Nora Staton Blatch, 1908;.  Mary Mayo, 1912; Marie Mosquinti, 1930. Children– Three. Education– Yale University, Ph.B., 1893; Ph.D., 1899. Began inventing mechanical devices while still a boy; patented some 300 inventions during his lifetime.  In 1907 patented his most important invention, the “Audion tube,” the elementary form of the vacuum radio tube, which was capable of more sensitive reception of wireless signals than any of the other receptors then in use.  Over the next few years DeForest developed and perfected Audion technology to amplify as well as transmit and receive radio signals–an essential development for both radio and television communication.  After failing in several attempts to form his own manufacturing company, DeForest sold his patents to communications firms for commercial development.  The Audion tube became the key component for all sophisticated radio, telephone, radar, television, and computer systems;  it remained in use until the invention of the transistor in 1947.  DeForest was also important for his early promotion and popularization of radio technology; he began public demonstrations of wireless telegraphy as early as 1902.  In 1910 he broadcast a live performance by Enrico Caruso at the Metropolitan Opera, the first production of its type.  In the 1920’s DeForest developed a system for recording and reproducing sound motion pictures, but the operating quality was poor and the system was not commercially successful.  Widely honored as the “father of radio” and the “grandfather of television,” DeForest was strongly though unsuccessfully supported for the Nobel Prize for Physics

American inventor (1873–1961)

Lee de Forest (August 26, 1873 – June 30, 1961) was an American inventor, electrical engineer and an early pioneer in electronics of fundamental importance. He invented the first practical electronic amplifier, the three-element "Audion" triodevacuum tube in 1906. This helped start the Electronic Age, and enabled the development of the electronic oscillator. These made radio broadcasting and long distance telephone lines possible, and led to the development of talking motion pictures, among countless other applications.

He had over 300 patents worldwide, but also a tumultuous career – he boasted that he made, then lost, four fortunes. He was also involved in several major patent lawsuits, spent a substantial part of his income on legal bills, and was even tried (and acquitted) for mail fraud.

Despite this, he was recognised for his pioneering work with the 1922 IEEE Medal of Honor, the 1923 Franklin InstituteElliott Cresson Medal and the 1946 American Institute of Electrical EngineersEdison Medal.

Early life

Lee de Forest was born in 1873 in Council Bluffs, Iowa, the son of Anna Margaret (née Robbins) and Henry Swift DeForest. He was a direct descendant of Jessé de Forest, the leader of a group of WalloonHuguenots who fled Europe in the 17th century due to religious persecution.

De Forest's father was a Congregational Church minister who hoped his son would also become a pastor. In 1879 the elder de Forest became president of the American Missionary Association's Talladega College in Talladega, Alabama, a school "open to all of either sex, without regard to sect, race, or color", and which educated primarily African-Americans. Many of the local white citizens resented the school and its mission, and Lee spent most of his youth in Talladega isolated from the white community, with several close friends among the black children of the town.

Lee de Forest (1873-1961) was an Americaninventor. His inventions helped to create radio and television. He is sometimes described as the "Father of Radio". In his lifetime, he had created over 300 inventions.

Early Life

He was born in 1873 in Council Bluffs, Iowa. His father was a minister. He studied at Yale University. He studied science and got a Ph.D. in 1899.

The Audion

In 1906, he invented a device called the Audion. It was a vacuum tube that could boost weak electrical signals. It was critical for making radio and television to function properly. It contained three parts: a filament, a plate, and a grid.

The filament heated up and produced electrons. The plate collected electrons. The grid in the center controlled the flow of electrons. It allowed the Audion to amplify signals. Audion was included in radios, televisions, and early computers. It helped make these inventions more practical and popular.

Radio and Television

He used Audion to create some of the early radiobroadcasts. In 1907, he broadcast music on the radio in New York City. He also broadcast from the Metropolitan Opera House.
