However, former New York City Mayor Vincent Impellitteri (1900-1987) popularized "unbought and unbossed" in 1950. Citations have also been found from the presidential campaign of Warren G. Harding (1920) and the New York City mayoral campaign of Fiorello La Guardia (1933)
Wikipedia: Shirley Chisholm
Shirley Anita Chisholm (née St. Hill; November 30, 1924 – January 1, 2005) was an American politician, educator, and author. In 1968, she became the first black woman elected to the United States Congress, and she represented New York's 12th congressional district for seven terms from 1969 to 1983. In 1972, she became the first black candidate for a major party's nomination for President of the United States, and the first woman to run for the Democratic Party's presidential nomination.
Chisholm wrote two autobiographical books.

The audience became impatient and as the crowds in the balcony started clapping Mr. Boehm stepped before the microphone and introduced the first speaker, Moses H. Grossman, the Recovery party candidate for Justice of the Supreme Court.
Judge Grossman evoked the first applause when he mentioned the name of Mr. McKee and then the names of the other principal candidates on the Recovery ticket.
"Each of them," he said, "was nominated solely by the petitions of the people and not by the hands of any political bosses. This is not a political campaign; this is a political revolution."
These men, he went on, "are running in spite of a stupid and arrogant political" hierarchy which opposed their candidacy. The Recovery party, he emphasized, stands for political independence and its candidates, when elected, will be "unbought and unbossed."

6 June 1952, New York (NY) Times, "Mayor Rejects Bid to Tammany Dinner" by James A. Hagerty, pg. 12, col. 5:
In an attempt to attain party harmony, Mr. DeSapio offered Mr. Impellitteri a Democratic nomination for Supreme Court Justice with oral assurance of a Liberal party endorsement after Mr. Impellitteri had announced his intention to run for Mayor on an independent ticket. Mr. Impellitteri's refusal of this offer enabled him to run as the "unbossed and unbought" candidate of the independent Experience party. He defeated Ferdinand Pecora, former Supreme Court Justice, the candidate of the Democratic and Liberal parties, by a plurality of 235,824.
24 September 1953, New York (NY) Times, pg. 1:
Meanwhile, posters of the Experience party, the Mayor's party in 1950, appeared in many places in the city. They have been pasted over the pre-primary posters and urge a vote for Mr. Impellitteri on Nov. 3 as the candidate who "cannot be bought or bossed."
William J. Donoghue, former secretary to Mayor Impellitteri, yesterday joined the staff of the headquarters of Robert F. Wagner Jr., Democratic nominee for Mayor, at the Biltmore Hotel. Mr. Conoghue is generally credited with having had a large part in electing Mr. Impellitteri in 1950 and with having invented the description of him as the "unbought and unbossed candidate."
