Motown singer Jimmy Ruffin has passed away at the age of 78.

The hit-making singer reportedly died on Monday, Nov. 17, in a Las Vegas hospital. Ruffin's children Philicia Ruffin and Jimmy Lee Ruffin, Jr. confirmed his passing in a statement.

"Jimmy Ruffin was a rare type of man who left his mark on the music industry," the siblings told CNN. "My family in its entirety is extremely upset over his death. He will truly be missed. We will treasure the many fond and wonderful memories we all have of him."

Ruffin was born in Collinsville, Mississippi. He moved to Detroit, the home of Motown, in the 1960s where he signed with the company's Miracle label.

Ruffin was often considered an underrated gem of the Motown family. His song "What Becomes of the Brokenhearted" was one of the company's greatest hits. However, Ruffin's talent was often overshadowed by his younger brother, David Ruffin, who found mega success as the lead singer of The Temptations.

Motown's founder, Berry Gordy, released a statement to Rolling Stone, declaring that "Jimmy Ruffin was a phenomenal singer."

"He was truly underrated because we were also fortunate to have his brother, David, as the lead singer of the Temptations, who got so much acclaim. Jimmy, as a solo artist, had 'What Becomes of the Brokenhearted,' one of the greatest songs put out by Motown and also one of my personal favorites," explained Gordy.

"He was a wonderful human being, quiet and unassuming, who touched many lives with his music, not just here in the states, but overseas, as well," said Gordy. "Jimmy Ruffin will always be a part of the Motown legacy, and I extend my sincere condolences to his family, friends and fans."

Ruffin's other songs include "Hold On (To My Love)," "I've Passed This Way Before," "Gonna Give Her All the Love I've Got," "Don't You Miss Me A Little Bit Baby" and "I'll Say Forever My Love."

Ruffin also served in the U.S. Army.
