Desi Arnaz Jr.

His older sister is actress Lucie Arnaz, who was born in 1951.

His birth was one of the most publicized in television history.

His parents were the stars of the television sitcom I Love Lucy, and Ball's pregnancy was part of the story line, which was considered daring in 1952.

The same day Ball gave birth to Desi Jr., the fictional Lucy Ricardo gave birth to "Little Ricky".

As a testament to how interested the American public was in Lucy's TV baby, Arnaz appeared on the cover of the very first issue of TV Guide with the headline "Lucy's $50,000,000 baby", ($0 in dollars) because revenue from advertising tie-ins was expected to top that mark.

Actor Richard Keith (a.k.a. Keith Thibodeaux) later portrayed "Little Ricky" in the TV series; Keith spent much time with Lucie and Desi Jr. in childhood and became close friends with the family, teaching Desi Jr. how to play drums.

Arnaz attended University High School in West Los Angeles.

At age 12, Arnaz was a drummer with Dino, Desi & Billy.

The others were Dean Paul Martin (son of Dean Martin) and Billy Hinsche.

Desiderio Alberto Arnaz IV (born January 19, 1953), better known as Desi Arnaz Jr., is an American retired actor and musician.

He is the son of Lucille Ball and Desi Arnaz.

Arnaz was born on January 19, 1953, at Cedars of Lebanon Hospital in Los Angeles.

The band scored two hit singles with "I'm a Fool" and "Not the Lovin' Kind" in 1965.

From 1968 to 1974, Desi Arnaz and his sister Lucie co-starred opposite their mother in Here's Lucy as her children.

In 1968, he had a guest-starring role as Jerry and Suzie's drum-playing friend Tommy in the episode, "The Hombre Who Came to Dinner: Part 2", from the show The Mothers-in-Law, executive-produced and directed by his father.

Arnaz has a daughter, Julia Arnaz, from a relationship with model Susan Callahan-Howe in 1968 when they were both 15 years old; Julia's relationship to Desi Jr. was proven by a paternity test in 1991.

Arnaz dated actress Patty Duke when he was 17 and she was 23.

In 1970, he appeared on The Brady Bunch episode "The Possible Dream".

He accompanied Duke to the 1970 Emmy Awards ceremony where she won the Emmy for Outstanding Single Performance.

The relationship became tabloid news and his mother did not approve of them together, and Duke became pregnant.

After they broke up, writer and music producer Michael Tell offered to marry Duke as a way out of the scandal.

He starred in the tearjerker movie Red Sky at Morning in 1971 with Richard Thomas, Richard Crenna and Claire Bloom.

His best chance at enduring Hollywood fame came in 1973, when he played the title role in the film Marco, a musical about the life of adventurer Marco Polo.

However, like most Hollywood musicals of that period, it failed to register at the box office.

In 1974, Arnaz played the title role in the Western movie Billy Two Hats with Gregory Peck.

In 1976, he appeared on two episodes of the television series, The Streets of San Francisco.

Arnaz also appeared in a 1976 episode of Saturday Night Live (SNL) hosted by both Desi Arnaz and Desi Arnaz Jr..

The younger Arnaz played Ricky Ricardo while Gilda Radner played Lucy in spoofs of supposed ill-fated pilots for I Love Lucy.

In 1977, he was the lead in the film Joyride opposite fellow children of famous actors Melanie Griffith, Robert Carradine, and Anne Lockhart.

Arnaz's acting extended into the late 1980s with various appearances on television, and a leading role in the series Automan, which ran from 1983 to 1984.

In 1992, he played his father in the movie The Mambo Kings, based on a Pulitzer Prize-winning novel that he felt treated his father with respect.

The film includes a scene in which Desi Jr., playing his father's character Ricky Ricardo, acts opposite his mother as Lucy Ricardo with film from the TV series intercut with the cast.

Between 1998 and 2010, he was touring with a new configuration of Dino, Desi & Billy called Ricci, Desi & Billy, featuring Arnaz reunited with Billy Hinsche, and joined by Ricci Martin (youngest son of Dean Martin).

The group performed original material as well as the songs the original band performed.

From about 2002 to 2007, he was vice-president of the board of Directors of the Lucille Ball–Desi Arnaz Center in Jamestown, New York.

He resigned over a dispute with the executive director over the center.

In 2007, Arnaz appeared at the 5th Annual TV Land Awards with his sister Lucie to accept the Legacy of Laughter award posthumously given to their mother.

Arnaz has also headlined Babalu: A Celebration of the Music of Desi Arnaz and his Orchestra with Lucie Arnaz, Raul Esparza, and Valarie Pettiford.

On October 15, 2011, Arnaz performed in Babalu at the Coolidge Auditorium of the Library of Congress.

The performance was in conjunction with the Library's Lucille Ball and Desi Arnaz Collection.
