Former WWE Tag Team Champion Jim 'The Anvil' Neidhart has passed away at the age of 63.

Neidhart was a legend in the pro wrestling business, who became most popular while teaming with Bret 'The Hitman' Hart as The Hart Foundation in the 1980s, winning the Tag Team Championship on two occasions. Prior to his alliance with The Hitman, Neidhart became a notable name competing for Hart Family's Stampede Wrestling, as well as various NWA promotions and New Japan Pro Wrestling.

In the early 1990s, the Hart Foundation amicably parted, but Anvil was left without a direction in the WWE, and briefly partnered with Bret's brother, Owen, but the team did not gain much steam. After a mildly successful WCW run, Anvil's career was revitalized when he returned to the WWE, siding with Owen Hart again during his feud with Bret.

Anvil left the WWE again for WCW, but was mostly used as an enhancement talent under a mask under the name "Who?" In 1997, Neidhart once again received a prominent spot in the WWE, as he was a member of the villainous Hart Foundation stable, led by Bret Hart, which included Owen, British Bulldog, and Brian Pillman.

Following his final WWE stint in 1997, Neidhart gave WCW one more try as he teamed with British Bulldog but mainly competed for independent promotions. He made an appearance in 2009 for Impact Wrestling (then known as TNA), defeating Jay Lethal. In 2013, Neidhart frequently tagged with British Bulldog's son, Harry Smith, and he also made an in-ring return in 2016 at the BCW Night of Legends event, teaming with Koko B. Ware and Frankie the Pizza Guy to defeat the Cash Masters and Nikolai Volkoff.

Over the past few years, Neidhart has been seen making appearances on WWE's Total Divas reality show, as his daughter Natalya has been a mainstay on the show since its inception in 2013.
