Hearts broke all over the world when Robin Williams passed away in August 2014. The beloved actor not only left behind a legacy of classic movies and philanthropy, but he also said goodbye to his three children: Zak, 35, Zelda, 28, and Cody, 26. Robin welcomed Zak with his first wife, Valerie Velardi, and Zelda and Cody with his second wife, Marsha Garces. The trio often accompanied their dad to red carpet events, and they frequently pay tribute to him on social media. July 21 marks what would have been Robin's 67th birthday, and we're honoring him by taking a look back at some of his sweetest family moments.
