Problem: Background: 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.
Context: 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.
Question: What kinds of things could be done with audio frequency amplification?
Answer: Telegraph Company was researching ways to amplify telephone signals

Problem: Background: Walston was born Herman Raymond Walston on November 2, 1914, in Laurel, Mississippi, the second son and youngest of three children born to lumberjack Harry Norman Walston (1881-1946) and Mittie (nee Kimball) Walston (December 25, 1883-August 16, 1950). He had an older sister, Carrie (1906-1982), and an older brother, Earl (February 4, 1908 - December 4, 1998). His family moved from Mississippi to New Orleans, Louisiana around 1925. He started acting at an early age, beginning his tenure as a spear carrier rounding out productions at many New Orleans theaters.
Context: From 1980-1992, Walston starred in 14 films, including Galaxy of Terror and Fast Times at Ridgemont High (as well as the 1986 television adaptation) as Mr. Hand. In a 1999 interview, Walston said that he was happy and relieved that when he walked down the street, young fans shouted at him "Mr. Hand" because he had finally torn away from his Martian role. In 1984, Walston played a judge on an episode of Night Court. Six years later, he made a guest appearance on an episode of L.A. Law. He later was hired for the role of Judge Henry Bone on Picket Fences; the character was originally a recurring role, but Walston proved to be so popular the character was later upgraded to a starring role.  He made an appearance in Star Trek: The Next Generation as Boothby, head groundskeeper at Starfleet Academy in San Francisco, and he reprised the character twice on Star Trek: Voyager, despite the series being set in a distant part of the galaxy. (The first time, he actually played an alien participating in a simulation of the Academy; the second appearance was in a dream sequence.) During his appearance on Star Trek: Voyager in "In the Flesh", he often had trouble with remembering his lines during long one-shot dialogue scenes, but while the cameraman was changing the film for the scene in the briefing room, he quoted a line from Hamlet. Robert Beltran then quoted the next line, and Walston the next. The two went on for several minutes, amazing the entire cast and crew. In a twist of fate Beltran had starred in the role of Luther Billis while in high school  In 1985, Walston made a brief appearance in the opening credits of Steven Spielberg's series Amazing Stories, as a caveman acting out a story for his tribe. Only a few seconds long, this performance began every episode of the subsequent series. In 1992, Walston played the role of Candy in the big-screen remake of John Steinbeck's Of Mice and Men with Gary Sinise and John Malkovich. He would work alongside Sinise again two years later in the miniseries adaptation of Stephen King's The Stand.  Walston was nominated three times for Best Supporting Actor in a Drama Series for his work on Picket Fences, winning twice, in 1995 and 1996. CBS cancelled the show after four seasons in 1996. Walston made a guest appearance in an episode of Dr. Quinn, Medicine Woman entitled "Remember Me", in which he portrayed the father of Jake Slicker, who was stricken with Alzheimer's disease.
Question: Did he do any stage work during this period?
Answer:
Walston was nominated three times for Best Supporting Actor in a Drama Series for his work on Picket Fences,
