Mary Redmond, founder of the Irish Hospice Foundation (IHF), has died aged 64.
Dr Redmond founded the IHF almost 30 years ago after being impressed by the quality of care that her father, Dr John Redmond, received "in the expert and loving hands" of staff at Our Lady's Hospice in Harold's Cross in Dublin.
Irish Hospice CEO Sharon Foley paid tribute to Dr Redmond, whom she described as "an inspirational and visionary leader and one of the founders of the hospice movement in Ireland".
"We are deeply saddened to hear of the news of Dr Redmond's passing. She had foresight, determination and generosity of spirit and we are very proud today to continue with her work," she added.
Dr Redmond was also a member of the RTÉ Authority.
In an interview marking the 20th birthday of the IHF in 2006 Dr Redmond said she had no idea when she started the process of setting up the Irish Hospice Foundation that it was going to become so big, and that the work was going to be so challenging.
Dr Redmond was conferred with a Doctor in Laws (LL.D) from Trinity College in 2014.
In 1999 she also established the Wheel, a support and representative body connecting community and voluntary organisations and charities across Ireland, which has evolved to become a resource centre and forum for the community and voluntary sector.
