The Defining Ages of the Prince of Darkness

Ozzy Osbourne’s life was a series of dramatic acts, each one beginning at a significant age. Understanding "how old was Ozzy Osbourne" at these junctures provides context for his legendary status and immense topical authority in rock history.

1. Age 19: The Birth of Black Sabbath (1968)

In 1968, John Michael Osbourne was just 19 years old when he co-founded the band that would change the face of music forever. Initially known as Earth, the group—featuring Tony Iommi, Geezer Butler, and Bill Ward—soon adopted the name Black Sabbath. At this tender age, Ozzy, the young vocalist from Aston, Birmingham, helped pioneer the heavy metal genre with their dark, blues-infused sound. The success of their 1970 debut album, *Black Sabbath*, and the iconic *Paranoid* later that year, established him as the genre’s foundational voice and the original "Prince of Darkness."

2. Age 31: The Solo Resurrection with *Blizzard of Ozz* (1980)

After being fired from Black Sabbath in 1979, a depressed and directionless Ozzy was staring into the void. By 1980, at the age of 31, he launched his solo career with the help of his future wife and manager, Sharon Arden (later Sharon Osbourne). The release of his debut solo album, *Blizzard of Ozz*, was a monumental comeback. Featuring the brilliant guitarist Randy Rhoads, the album gave the world enduring anthems like "Crazy Train" and "Mr. Crowley," proving his creative force extended far beyond his original band and cementing his status as a solo rock icon.

While he kept the diagnosis private for years, the disease would gradually become the central focus of his later life, leading to numerous health complications and mobility challenges that he would openly discuss in his final years. This marked the beginning of his quiet, decades-long battle with a debilitating neurological condition.

5. Age 71: Going Public with His Health Battle (2020)

Following a serious fall in 2019 that aggravated injuries from a 2003 ATV accident, Ozzy’s health struggles became impossible to hide. In January 2020, at the age of 71, he publicly revealed his Parkinson’s diagnosis on *Good Morning America*.
