IN: 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.

IN: Brian Douglas Wilson (born June 20, 1942) is an American musician, singer, songwriter, and record producer who co-founded the Beach Boys. After signing with Capitol Records in 1962, Wilson wrote or co-wrote more than two dozen Top 40 hits for the group. In addition to his lifelong struggles with mental illness, Wilson is known for his unorthodox approaches to pop composition and mastery of recording techniques, and he is widely acknowledged as one of the most innovative and significant songwriters of the late 20th century. The Beach Boys were formed by Brian, his brothers Carl and Dennis, their cousin Mike Love, and friend Al Jardine.

Brian Douglas Wilson was born on June 20, 1942, at Centinela Hospital in Inglewood, California, the eldest son of Audree Neva (nee Korthof) and Murry Wilson. His two younger brothers were Dennis and Carl. He has English, Swedish, Dutch, German, and Irish ancestry. When Brian was two, the family moved from Inglewood to 3701 West 119th Street in nearby Hawthorne, California. Speaking of Brian's unusual musical abilities prior to his first birthday, his father said that, as a baby, he could repeat the melody from "When the Caissons Go Rolling Along" after only a few verses had been sung by the father. Murry Wilson said, "He was very clever and quick. I just fell in love with him." At about age two, Brian heard George Gershwin's Rhapsody in Blue, which had an enormous emotional impact on him. A few years later, he was discovered to have diminished hearing in his right ear. The exact cause of this hearing loss is unclear, though theories range from him simply being born partially deaf to a blow to the head from his father, or a neighborhood bully, being to blame. While Brian's father Murry was ostensibly a reasonable provider, he was often abusive. A minor musician and songwriter, he also encouraged his children in this field in numerous ways. At an early age, Brian was given six weeks of lessons on a "toy accordion" and, at seven and eight, sang solos in church with a choir behind him. At Hawthorne High School, Brian was on the football team as a quarterback, played baseball and was a cross-country runner in his senior year. He sang with various students at school functions and with his family and friends at home, teaching his two brothers harmony parts that all three would then practice. He also played piano obsessively after school, deconstructing the harmonies of the Four Freshmen by listening to short segments of their songs on a phonograph, then working to recreate the blended sounds note by note on the keyboard. He received a Wollensak tape recorder on his 16th birthday, allowing him to experiment with recording songs and early group vocals. Surviving home tapes document his initial efforts singing with various friends and family. In his senior year at Hawthorne High, in addition to classroom music studies, he sang at lunch time with friends like Keith Lent and Bruce Griffin. Brian and Keith worked on a revised version of the tune "Hully Gully" to support the campaign of a classmate named Carol Hess when she ran for senior class president. Enlisting his cousin and frequent singing partner Mike Love as well as his own brother Carl, Brian's next public performance featured more ambitious arrangements at a fall arts program at his high school. To entice Carl into the group, Brian named the newly formed membership Carl and the Passions. The performance featured tunes by Dion and the Belmonts and the Four Freshmen ("It's a Blue World"), the latter of which proved difficult for the ensemble. The event was notable for the impression which it made on another musician and classmate of Brian in the audience that night, Al Jardine, who would join the three Wilson brothers and Mike Love a few years later in the Beach Boys.
