Ann Landers was a pen name created by Chicago Sun-Times advice columnist Ruth Crowley in 1943 and taken over by Eppie Lederer in 1955. For 56 years, the Ask Ann Landers syndicated advice column was a regular feature in many newspapers across North America. Due to this popularity, 'Ann Landers', though fictional, became something of a national institution and cultural icon.

The creator of the 'Ann Landers' pseudonym was Ruth Crowley, a Chicago nurse who had been writing a child-care column for the Sun since 1941. She chose the pseudonym at random — borrowing the surname 'Landers' from a family friend — in order to prevent confusion between her two columns. Unlike Lederer, Crowley kept her identity as Landers secret, even enjoining her children to help her keep it quiet. Crowley took a three-year break from writing the column from 1948 until 1951. After 1951 she continued the column for the Chicago Sun-Times and in syndication (since 1951) to 26 other newspapers until her death, aged 48, on July 20, 1955. Crowley spent a total of nine years writing advice as 'Ann Landers'.

Fred Allen (born John Florence Sullivan, May 31, 1894 – March 17, 1956) was an American comedian whose absurdist, topically pointed radio show (1932–1949) made him one of the most popular and forward-looking humorists in the so-called classic era of American radio.

His best-remembered gag was his long-running mock feud with friend and fellow comedian Jack Benny, but it was only part of his appeal; radio historian John Dunning (in On the Air: The Encyclopedia of Old-Time Radio) wrote that Allen was radio's most admired comedian and most frequently censored. A master ad libber, Allen often tangled with his network's executives (and often barbed them on the air over the battles), while developing routines the style and substance of which influenced contemporaries and futures among comic talents, including Groucho Marx, Stan Freberg, Henry Morgan and Johnny Carson, but his fans also included President Franklin D. Roosevelt, and novelists William Faulkner, John Steinbeck and Herman Wouk (who began his career writing for Allen).

Albert Ellis (September 27, 1913 – July 24, 2007) was an American psychologist who in 1955 developed Rational Emotive Behavior Therapy (REBT). He held M.A. and Ph.D. degrees in clinical psychology from Columbia University and American Board of Professional Psychology (ABPP). He also founded and was the president emeritus of the New York City-based Albert Ellis Institute. He is generally considered to be one of the originators of the cognitive revolutionary paradigm shift in psychotherapy and the founder of cognitive-behavioral therapies. Based on a 1982 professional survey of USA and Canadian psychologists, he was considered as the second most influential psychotherapist in history (Carl Rogers ranked first in the survey; Sigmund Freud was ranked third). Prior to his death, Psychology Today described him as the “greatest living psychologist.”

Ellis was born to a Jewish family in Pittsburgh, Pennsylvania, USA, in 1913. He was the eldest of three children. Ellis' father was a businessman, often away from home on business trips, who reportedly showed only a modicum of affection to his children.

Howard Allan Stern (born January 12, 1954) is an American radio personality, television host, author, actor and photographer best known for his radio show which was nationally syndicated from 1986 to 2005. He gained wide recognition in the 1990s where he was labeled a "shock jock" for his outspoken and sometimes controversial style. Stern has been exclusive to Sirius XM Radio, a subscription-based satellite radio service, since 2006. The son of a former recording and radio engineer, Stern wished to pursue a career in radio at the age of five. While at Boston University he worked at the campus station WTBU before a brief stint at WNTN in Newton, Massachusetts.

He developed his on-air personality when he landed positions at WRNW in Briarcliff Manor, WCCC in Hartford and WWWW in Detroit. In 1981, he was paired with his current newscaster and co-host Robin Quivers at WWDC in Washington, D.C. Stern then moved to WNBC in New York City in 1982 to host afternoons until his firing in 1985. He re-emerged on WXRK that year, and became one of the most popular radio personalities during his 20-year tenure at the station. Stern's show is the most-fined radio program, after the Federal Communications Commission (FCC) issued fines to station licensees for allegedly indecent material that totaled $2.5 million. Stern has won Billboard's Nationally Syndicated Air Personality of the Year award eight times, and is one of the highest-paid figures in radio.
