What did Leo Bonn green plaque do at 22 Upper Brook Street?

The Story

# Leo Bonn at 22 Upper Brook Street On a June morning in 1911, within the walls of this elegant Mayfair townhouse at 22 Upper Brook Street, Leo Bonn—then already in his eighth decade—brought his lifelong vision into concrete reality by founding what would become the Royal National Institute for Deaf People. This wasn't merely an office opening or a bureaucratic registration; it was the crystallization of decades of advocacy and determination into an institution that would transform deaf education and support across Britain. Standing here at this address, you're at the precise birthplace of an organization that would grow to serve hundreds of thousands, beginning from this single Georgian building where Bonn established the foundational systems, connections, and mission that still define the charity today. For Bonn himself, who had dedicated so much of his later life to championing deaf causes, this moment represented not retirement but the ultimate achievement—proof that one person's commitment, pursued with unwavering focus, could establish something that would outlive him by generations and continue serving the deaf community for centuries to come.
