Len Goodman, the distinguished dance judge best known for his roles on "Dancing with the Stars" and "Strictly Come Dancing," has passed away at the age of 78, according to his agent. Goodman's death was peaceful, and he had been previously diagnosed with bone cancer.

With a background as a professional ballroom dancer and British champion, Goodman served as the head judge on "Strictly Come Dancing" for 12 years since its premiere on BBC in 2004. The celebrity dance competition quickly became a beloved program on the network.

The English judge's witty commentary and charming Cockney accent won over viewers. He often delivered memorable lines while critiquing performances, comparing dancers to "butter on a crumpet" or "sizzling sausages on a barbecue."

Goodman also held the position of head judge on the American edition of the show, "Dancing With the Stars," on ABC for 15 years before retiring in November. For some time, he judged both the British and American versions of the show, traveling between the two countries each week.

British presenter Esther Rantzen noted that Goodman was both surprised and delighted by his later-in-life success, attributing part of his appeal in the United States to his distinct Britishness.

Apart from his work on dance shows, Goodman also hosted BBC radio programs and produced television documentaries, including one about the Titanic's sinking. Earlier in his life, he had worked as a shipyard welder for the company that constructed the ill-fated ship.

BBC director-general Tim Davie expressed the organization's sadness over Goodman's passing, stating that he was a beloved entertainer who felt like part of the family to millions. Davie credited Goodman's contributions to the success of "Strictly Come Dancing."

Goodman was honored with the Carl Alan Award for his outstanding contributions to dance and owned the Goodman Academy dance school in southern England.

Upon his retirement, fellow judges and show host Tyra Banks celebrated Goodman as a "legend." Many professional dancers on the show, including co-judge Derek Hough, had been evaluated by Goodman during their childhoods. Banks commended Goodman for inspiring generations of dancers worldwide through his passion, expertise, and keen eye for excellence.
