A consultant who launched a campaign encouraging health workers to introduce themselves to patients has died after a five-year cancer fight.
Dr Kate Granger's "Hello, My Name Is ..." campaign was described as "inspirational" and won the backing of many politicians and celebrities.
She had the idea in 2013 while receiving treatment in hospital, when she said she made the "stark observation" that many staff did not introduce themselves to people before treating them.
Her husband Chris Pointon, whom she credited with supporting her throughout the campaign, confirmed in a tweet that his wife had died on Saturday "peacefully & surrounded by loved ones".
Her campaign received support from Health Secretary Jeremy Hunt, NHS medical director Sir Bruce Keogh and former Top Gear presenter Jeremy Clarkson.
She achieved her goal of raising £250,000 for Yorkshire Cancer Centre just days before her death at the age of 34.
Kate, from Wakefield, West Yorkshire, was diagnosed with cancer in 2011 but described herself as an optimist.
Speaking last year she said: "I really hope my legacy will be putting compassionate practice right at the heart of healthcare delivery every single day."
Thousands of people, including many medical professionals, are paying tribute on Twitter and honouring the legacy she has left.
