The move comes after the newly public company was chastised for having no female directors.

Six months after activists criticized Facebook for an all-male boardroom, the company said Monday it has made COO Sheryl Sandberg its first female director.

"Sheryl has been my partner in running Facebook and has been central to our growth and success over the years," CEO Mark Zuckerberg said.

Zuckerberg founded Facebook in 2004 and Sandberg, 42, joined the company four years later after quitting Google.

Shares of Facebook, which went public last month at $38 apiece, closed 3 percent lower on Monday at $32.06.

Sandberg also serves on the board of the Walt Disney Co.

"Her understanding of our mission and long-term opportunity and her experience both at Facebook and on public company boards makes her a natrual fit for our board," Zuckerberg said.
