Some context: Lee de Forest was born in 1873 in Council Bluffs, Iowa, the son of Anna Margaret (nee Robbins) and Henry Swift DeForest. He was a direct descendant of Jesse de Forest, the leader of a group of Walloon Huguenots 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.
One of de Forest's areas of research at Federal Telegraph was improving the reception of signals, and he came up with the idea of strengthening the audio frequency output from a grid Audion by feeding it into a second tube for additional amplification. He called this a "cascade amplifier", which eventually consisted of chaining together up to three Audions.  At this time the American Telephone and Telegraph Company was researching ways to amplify telephone signals to provide better long-distance service, and it was recognized that de Forest's device had potential as a telephone line repeater. In mid-1912 an associate, John Stone Stone, contacted AT&T to arrange for de Forest to demonstrate his invention. It was found that de Forest's "gassy" version of the Audion could not handle even the relatively low voltages used by telephone lines. (Due to the way he constructed the tubes, de Forest's Audions would cease to operate with too high a vacuum.) However, careful research by Dr. Harold D. Arnold and his team at AT&T's Western Electric subsidiary determined that by improving the tube's design, it could be more fully evacuated, and the high vacuum allowed it to successfully operate at telephone line voltages. With these changes the Audion evolved into a modern electron-discharge vacuum tube, using electron flows rather than ions. (Dr. Irving Langmuir at the General Electric Corporation made similar findings, and both he and Arnold attempted to patent the "high vacuum" construction, but the U.S. Supreme Court ruled in 1931 that this modification could not be patented).  After a delay of ten months, in July 1913 AT&T, through a third party who disguised his link to the telephone company, purchased the wire rights to seven Audion patents for $50,000. De Forest had hoped for a higher payment, but was again in bad financial shape and was unable to bargain for more. In 1915, AT&T used the innovation to conduct the first transcontinental telephone calls, in conjunction with the Panama-Pacific International Exposition at San Francisco.

At the 1904 Louisiana Purchase Exposition, Valdemar Poulsen had presented a paper on an arc transmitter, which unlike the discontinuous pulses produced by spark transmitters, created steady "continuous wave" signals that could be used for amplitude modulated (AM) audio transmissions. Although Poulsen had patented his invention, de Forest claimed to have come up with a variation that allowed him to avoid infringing on Poulsen's work. Using his "sparkless" arc transmitter, de Forest first transmitted audio across a lab room on December 31, 1906, and by February was making experimental transmissions, including music produced by Thaddeus Cahill's telharmonium, that were heard throughout the city.  On July 18, 1907, de Forest made the first ship-to-shore transmissions by radiotelephone -- race reports for the Annual Inter-Lakes Yachting Association (I-LYA) Regatta held on Lake Erie -- which were sent from the steam yacht Thelma to his assistant, Frank E. Butler, located in the Fox's Dock Pavilion on South Bass Island. De Forest also interested the U.S. Navy in his radiotelephone, which placed a rush order to have 26 arc sets installed for its Great White Fleet around-the-world voyage that began in late 1907. However, at the conclusion of the circumnavigation the sets were declared to be too unreliable to meet the Navy's needs and removed.  The company set up a network of radiotelephone stations along the Atlantic coast and the Great Lakes, for coastal ship navigation. However, the installations proved unprofitable, and by 1911 the parent company and its subsidiaries were on the brink of bankruptcy.

Some context: Kisan Baburao Hazare was born on 15 June 1937 (some sources say 15 January 1940) in Bhingar, near Ahmednagar. He was the eldest son of Baburao Hazare and Laxmi Bai. He has two sisters and four brothers. He later adopted the name Anna, which in Marathi means "elder person" or "father".
Hazare and the youth group decided to take up the issue of alcoholism to drive a process of reform. At a meeting conducted in the temple, the villagers resolved to close down liquor dens and ban alcohol in the village. Since these resolutions were made in the temple, they became, in a sense, religious commitments. Over thirty liquor brewing units voluntarily closed their establishments. Those who did not succumb to social pressure were forced to close their businesses when the youth group smashed their premises. The owners could not complain as their businesses were illegal.  Once 3 drunken villagers were tied to pillars and then flogged, personally by Hazare with his army belt. He justified this punishment by stating that "rural India was a harsh society", and that  Doesn't a mother administer bitter medicines to a sick child when she knows that the medicine can cure her child? The child may not like the medicine, but the mother does it only because she cares for the child. The alcoholics were punished so that their families would not be destroyed.  Hazare appealed to the government of Maharashtra to pass a law whereby prohibition would come into force in a village if 25% of the women in the village demanded it. In 2009 the state government amended the Bombay Prohibition Act, 1949 to reflect this.  It was decided to ban the sale of tobacco, cigarettes, and beedies (an unfiltered cigarette where the tobacco is rolled in tendu also known as Diospyros melanoxylon leaves instead of paper) in the village. To implement this resolution, the youth group performed a unique "Holi" ceremony twenty two years ago. The festival of Holi is celebrated as a symbolic burning of evil. The youth group brought all the tobacco, cigarettes, and beedies from the shops in the village and burnt them in a Holi fire. Tobacco, cigarettes, or beedies are no longer sold.
