Gilbert Baker, the man who in 1978 created the rainbow flag, an iconic symbol of gay pride all over the world, died in his sleep on Thursday night at the age of 65. His death has inspired impassioned tributes both on and offline.

On Friday, hundreds of grievers took to San Francisco's Castro District, known as one of the United States' first and most vibrant gay neighborhoods, to honor Baker. Among the attendees was Cleve Jones, another famous gay rights activist and author of the book "When We Rise: My Life in the Movement," which has since been turned into a miniseries on ABC,

Many more, including Jones, took to social media platforms such as Facebook and Twitter to share news articles about Baker's passing, as well as to write kind tributes to the man who created one of the LGBT community's most enduring symbols.

Remembering #GilbertBaker for his lifelong dedication to the cause for inclusion& equality. His leadership will never be forgotten. RIP πŸ³οΈβ€πŸŒˆ
