Leading figures from across Silicon Valley gathered at Stanford University for a memorial service honoring David Goldberg, a popular start-up executive and husband of "Lean In" author Sheryl Sandberg.

The 47-year-old Goldberg, who was CEO of online start-up SurveyMonkey, died in an accident while exercising at a Mexican vacation resort on Friday. Authorities said he apparently slipped on a treadmill and struck his head.

President Obama extended his sympathies on Facebook this week, joining a number of well-known Silicon Valley figures including Facebook CEO Mark Zuckerberg, who is Sandberg's boss.

Mourners streamed into a 1,700-seat auditorium at Stanford, in the heart of Silicon Valley, for a closed service. An e-mail invitation asked men to attend without neckties, "in keeping with Dave's lifelong hatred of ties."

"He was a perfect cross between a teddy bear and a tiger," former Yahoo President Sue Decker wrote on a tribute page for Goldberg, in a description echoed by others who knew him. Other tributes to Goldberg described his low-key humor, love for the Minnesota Vikings and his enthusiasm for playing poker.

In addition to Sandberg, Goldberg, who grew up in Minneapolis, is survived by their children and his mother, Paula Goldberg, executive director of PACER Center in the Twin Cities.

'Wedding Singer' rapper dies at 101

Ellen Albertini Dow, a feisty character actress best known for her salty rendition of "Rapper's Delight" in "The Wedding Singer," has died. She was 101. Her agent, Juliet Green, confirmed that Dow died Monday. Her breakout rap in "The Wedding Singer" led to memorable and often foul-mouthed character roles in films like "Wedding Crashers," ''Road Trip" and "54," as the drug-addled party girl Disco Dottie. Dow's numerous television credits include "Seinfeld" and "New Girl." Dow didn't begin her professional acting career until she was in her 70s, when she got her first job on "The Twilight Zone."
