His unrivaled affiliation with the studio began in 1928 in his Florida hometown when a silent film he saw at a Paramount-owned theater inspired him to ask for a job. At age 10, he was hired to hand out fliers.
As a movie-struck teenager, he bought a one-way ticket to Hollywood in the late 1930s, knocked on the studio's famous gates and was put to work in the mailroom. He became a studio publicist and by the late 1950s rose to producer.
As the decades passed, Lyles became famous for his longevity at Paramount, marking 85 years at the studio in May. He eventually functioned as an unofficial goodwill ambassador, representing the studio at various events, where he might regale guests with first-hand recollections of such Hollywood legends as Mae West, W.C. Fields and Steve McQueen.
Lyles, who still maintained an office on the Paramount lot, died Friday night at his home in Bel-Air, said his wife, Martha Lyles. He was 95 and had been in declining health in the last year.
"His history in the movie business is certainly unique," Sherry Lansing, then chairman of Paramount's motion picture division, told The Times in 1998. "There's nobody I met who doesn't love him, and there are very few people I've met who don't know him."
He was a walking repository of Hollywood history, much of it his own. He once counted Ronald Reagan and James Cagney among his best friends.
The gentlemanly and gregarious Lyles, deeply tanned and typically clad in an immaculate suit and crisp white shirt, was the last link on the lot to Paramount's golden era and to such stars as Gary Cooper, Bing Crosby, Barbara Stanwyck and Dorothy Lamour.
As Lyles often put it, he "had the shortest resume in Hollywood history."
At Paramount, he was once an office boy for studio founders Adolph Zukor and Cecil B. DeMille.
"Looking back on those two giants of Hollywood, I know how fortunate I was to be sort of adopted by them," Lyles told The Times in May.
Eventually he handled publicity for more than 70 films at the studio and made his debut as a producer on the only feature that Cagney directed, the 1957 crime drama "Short Cut to Hell."
"It was a little gangster picture," Lyles had said. "He wouldn't accept any money for doing it."
Among western-film buffs, Lyles was best known for producing a string of low-budget westerns in the 1960s that included "Young Fury," starring Rory Calhoun and Virginia Mayo, and "Waco" with Howard Keel and Jane Russell.
As of 2006 – the year he turned 88 – Lyles was still active in Hollywood, serving as a consulting producer on the HBO western series "Deadwood."
In later years, he was often interviewed for television documentaries chronicling the careers of Clara Bow, DeMille and Marlene Dietrich. And he was frequently called upon to deliver eulogies for such famous friends as Bob Hope and Donald O'Connor.
The walls of his large office on the fourth floor of the William S. Hart Building – once occupied by his friend Fred Astaire – were covered with framed photos of him with his celebrity friends.
Next to his large desk was a hand-cranked movie camera used on Paramount's Oscar-winning silent film "Wings," a World War I flying epic.
And therein lies the beginning of Lyles' Paramount story.
He was born Andrew Craddock Lyles Jr. on May 17, 1918, in Jacksonville, Fla. At 10, he found his future when his local theater screened "Wings" and he pluckily inquired about employment.
