Richard Briers became an Alzheimer's Society ambassador in 2007, after his poignant role in the TV drama Dad where he played the husband of a person with dementia.
Richard Briers was a keen and committed campaigner for Alzheimer's Society. In his role as an ambassador Richard has used his high profile and wit to support other families facing their own battles with the condition.
From lobbying MPs on the injustice of charging for life-enhancing dementia treatments to delivering some of the most entertaining after lunch speeches, Richard always sought to raise the profile of dementia whenever he could.
From all his friends and fans at Alzheimer's Society, our deepest condolences go to his wife Annie and his two daughters, Lucy and Katie.
