101-year-old Florence Detlor graduated Occidental College in 1932, likes books, and lives in Menlo Park, California. She has an interesting title, as well: Oldest registered Facebook user.

Or so says Facebook COO Sheryl Sandberg. Detlor visited her and CEO Mark Zuckerberg yesterday, and Sandberg posted a photo of it on Facebook.

“Honored to meet Florence Detlor, who at 101 years old is the oldest registered Facebook user. Thank you for visiting us Florence,” she said in a post.

Reports last year noted a significant rise in social media use by seniors. One Pew report noted a 60% increase year-over-year in social media use by those aged 50-64.

Sandberg’s post seems to have motivated some users to get their grandparents and great grandparents on Facebook. “Ok, so now I’m feeling competitive and ready to get my grandma on Facebook,” said one user. “She’s 103!”
