Top Silicon Valley leaders and other friends of former Apple CEO Steve Jobs gathered in Memorial Church Sunday evening to honor the local tech giant. Jobs died on Oct. 5 at the age of 56 after a years-long battle with pancreatic cancer.

Ninety minutes before the 6:30 p.m. service, black-clad Secret Service Guards cleared out the Main Quad, walled off the rear entrance of the church and guarded the Cantor Arts Center, which hosted a post-service reception and dinner. Palm Drive was closed to unauthorized traffic, and a fleet of shuttle buses, dark stretch SUVs and golf carts transported mourners to the center of campus. Candles lined sidewalks across the Oval leading to Cantor.

“Steve Jobs is one of my heroes,” said Dr. David Agus, one of Jobs’ oncologists. “I’ve been friends with him for several years and to be here is almost surreal, but it’s exciting that we get to hear more stories and talk about Steve in a collective group.”

The memorial also drew national figures from the political arena, including Secretary of State Hillary Clinton and former President Bill Clinton, former Secretary of State Condoleezza Rice, former Vice President Al Gore and Chicago mayor Rahm Emanuel. Gore is a board member at Apple and Jobs was a significant donor to Emanuel’s campaign.

Secret Service officials confirmed that Congresswoman Nancy Pelosi, California Governor Jerry Brown and California Lieutenant Governor Gavin Newsom also attended.

Google CEO Larry Page and his wife Lucinda “Lucy” Southworth were also in attendance, as were media mogul Rupert Murdoch, Intuit Chairman Bill Campbell, actor Tim Allen and Adobe co-founders Chuck Geschke and John Warnock.
