Question:
Lyman Frank Baum (May 15, 1856 - May 6, 1919), better known as L. Frank Baum, was an American author chiefly famous for his children's books, particularly The Wonderful Wizard of Oz and its sequels. He wrote a total of 14 novels in the Oz series, plus 41 other novels, 83 short stories, over 200 poems, and at least 42 scripts. He made numerous attempts to bring his works to the stage and the nascent medium of film; the 1939 adaptation of the first Oz book would become a landmark of 20th century cinema. His works anticipated such century-later commonplaces as television, augmented reality, laptop computers (The Master Key), wireless telephones (Tik-Tok of Oz), women in high-risk and action-heavy occupations (Mary Louise in the Country), police corruption and false evidence (Phoebe Daring), and the ubiquity of advertising on clothing (Aunt Jane's Nieces at Work).
Two years after Wizard's publication, Baum and Denslow teamed up with composer Paul Tietjens and director Julian Mitchell to produce a musical stage version of the book under Fred R. Hamlin. Baum and Tietjens had worked on a musical of The Wonderful Wizard of Oz in 1901 and based closely upon the book, but it was rejected. This stage version opened in Chicago in 1902 (the first to use the shortened title "The Wizard of Oz"), then ran on Broadway for 293 stage nights from January to October 1903. It returned to Broadway in 1904, where it played from March to May and again from November to December. It successfully toured the United States with much of the same cast, as was done in those days, until 1911, and then became available for amateur use. The stage version starred Anna Laughlin as Dorothy Gale, alongside David C. Montgomery and Fred Stone as the Tin Woodman and Scarecrow respectively, which shot the pair to instant fame.  The stage version differed quite a bit from the book, and was aimed primarily at adults. Toto was replaced with Imogene the Cow, and Tryxie Tryfle (a waitress) and Pastoria (a streetcar operator) were added as fellow cyclone victims. The Wicked Witch of the West was eliminated entirely in the script, and the plot became about how the four friends were allied with the usurping Wizard and were hunted as traitors to Pastoria II, the rightful King of Oz. It is unclear how much control or influence Baum had on the script; it appears that many of the changes were written by Baum against his wishes due to contractual requirements with Hamlin. Jokes in the script, mostly written by Glen MacDonough, called for explicit references to President Theodore Roosevelt, Senator Mark Hanna, Rev. Andrew Danquer, and oil magnate John D. Rockefeller. Although use of the script was rather free-form, the line about Hanna was ordered dropped as soon as Hamlin got word of his death in 1904.  Beginning with the success of the stage version, most subsequent versions of the story, including newer editions of the novel, have been titled "The Wizard of Oz", rather than using the full, original title. In more recent years, restoring the full title has become increasingly common, particularly to distinguish the novel from the Hollywood film.  Baum wrote a new Oz book, The Marvelous Land of Oz, with a view to making it into a stage production, which was titled The Woggle-Bug, but Montgomery and Stone balked at appearing when the original was still running. The Scarecrow and Tin Woodman were then omitted from this adaptation, which was seen as a self-rip-off by critics and proved to be a major flop before it could reach Broadway. He also worked for years on a musical version of Ozma of Oz, which eventually became The Tik-Tok Man Of Oz. This did fairly well in Los Angeles, but not well enough to convince producer Oliver Morosco to mount a production in New York. He also began a stage version of The Patchwork Girl of Oz, but this was ultimately realized as a film.

Answer the question at the end by quoting:

Thompson was born in Sheffield, Alabama, on August 19, 1942, the son of Ruth Inez (nee Bradley) and Fletcher Session Thompson (born Lauderdale County, Alabama, August 26, 1919, died Lawrenceburg, Tennessee, May 27, 1990), who was an automobile salesman. Thompson had English and distant Dutch ancestry. He attended public school in Lawrenceburg, graduating from Lawrence County High School, where he played high-school football. Thereafter, he worked days in the local post office, and nights at the Murray bicycle assembly plant.
In 1973, Thompson was appointed minority counsel to assist the Republican senators on the Senate Watergate Committee, a special committee convened by the U.S. Senate to investigate the Watergate scandal. Thompson was sometimes credited for supplying Republican Senator Howard Baker's famous question, "What did the President know, and when did he know it?" This question is said to have helped frame the hearings in a way that eventually led to the downfall of President Richard Nixon.  A Republican staff member, Donald Sanders, found out about the White House tapes and informed the committee on July 13, 1973. Thompson was informed of the existence of the tapes, and he, in turn, informed Nixon's attorney, J. Fred Buzhardt. "Even though I had no authority to act for the committee, I decided to call Fred Buzhardt at home," Thompson later wrote, "I wanted to be sure that the White House was fully aware of what was to be disclosed so that it could take appropriate action."  Three days after Sanders's discovery, at a public, televised committee hearing, Thompson asked former White House aide Alexander Butterfield the famous question, "Mr. Butterfield, were you aware of the existence of any listening devices in the Oval Office of the President?" thereby publicly revealing the existence of tape recordings of conversations within the White House. National Public Radio later called that session and the discovery of the Watergate tapes "a turning point in the investigation."  Thompson's appointment as minority counsel to the Senate Watergate committee reportedly upset Nixon, who believed Thompson was not skilled enough to interrogate unfriendly witnesses and would be outfoxed by the committee Democrats. According to historian Stanley Kutler, however, Thompson and Baker "carried water for the White House, but I have to give them credit--they were watching out for their interests, too... They weren't going to mindlessly go down the tubes [for Nixon]." When the Watergate investigation began to pick up speed, tapes revealed that Nixon remarked to his then-Chief of Staff Alexander Haig, "Oh shit, he's dumb as hell."  Journalist Scott Armstrong, a Democratic investigator for the Senate Watergate Committee, is critical of Thompson for having disclosed the committee's knowledge of the tapes to Buzhardt during an ongoing investigation, and says Thompson was "a mole for the White House" and that Thompson's actions gave the White House a chance to destroy the tapes. Thompson's 1975 book At That Point in Time, in turn, accused Armstrong of having been too close to The Washington Post's Bob Woodward and of leaking committee information to him. In response to renewed interest in this matter, in 2007 during his presidential campaign, Thompson said, "I'm glad all of this has finally caused someone to read my Watergate book, even though it's taken them over 30 years."
