Apple's departed: Here's everyone who's left Apple recently

Tom Gruber was one of the three founders who created Siri as a San Jose, Calif startup that was developed with the help of the Stanford University-affiliated SRI Research lab.

Apple acquired Siri for a reported $200 million in 2010, and the namesake virtual assistant made its debut on the iPhone 4, the following year. Gruber stayed at Apple years longer than his cofounder and was the head of the Siri Advanced Development team at Apple. But while Apple was early to market with a virtual assistant, it soon was competing, and by some estimates, lagging competitors like Google and Amazon.

According to a report in The Information, Gruber left to retire and pursue personal interests in ocean conservation and photography.

Williams had a big hand in Apple's products before he even worked at Apple, having previously worked at chip company ARM, whose processors powered the first iPhones. He joined Apple in 2010, and oversaw the firm's move to making its own processors, as the senior director of platform architecture for the company's CPUs.

While Williams' departure in March 2019 was a big loss for Apple, the company has since hired Mike Filipo, another chip hot shot from ARM.

Prakash oversaw the search engines that power Spotlight, Safari, and Siri, on iOS and on MacOS, and left Apple in July 2018 — around the same time that Siri cofounder Tom Gruber left the company.

Prakash joined Apple in 2013, when Apple acquired Topsy Labs, a social media and analytics search engine that he founded.

Jimmy Iovine was never a lifer at Apple, and it was not much of a surprise when he stepped back from his day to day role at the company in March 2018. An iconic figure in the music industry, who was the producer for artists from Stevie Nick to Eminem, Iovine joined when Apple acquired Beats in 2014 for $3 billion.

He then became the public face of Apple's then-nascent music streaming service, bringing his experience and connections in the music industry.

Ive is practically synonymous with Apple. The British designer joined Apple in 1992, working on pioneering products like the Newton.

When Apple founder Steve Jobs returned in 1997, Ive became Jobs' most trusted lieutenant and emerged as the creative force that drove the next two decades of dominance, with iconic products like the iPod, iPhone, and iPad.

Apple has a deep bench of talent and a strong line-up of senior leaders, including Apple head of internet software and services Eddy Cue, software engineering boss Craig Federighi, and CFO Luca Maestri. But some of them have been around for a long time. With the departure of Ive, it's natural to wonder if some other veterans will decide it's a good time to follow his lead.
