A doctor who helped lead the campaign to prevent the addition of fluoride to drinking water has died at the age of 97.
Walter Yellowlees, known as Watty, spent more than 30 years working in Highland Perthshire.
Mr Yellowlees encouraged his patients to exercise and take up eating habits now enshrined in the Five-a-Day campaign.
Born in Stirling in 1917, he arrived just weeks after his namesake uncle, Walter Primrose, was killed in action in the First World War.
Mr Yellowlees was educated at Merchiston Castle School, Edinburgh, before graduating from Edinburgh University in 1941.
His first appointment was as a house surgeon at Stirling Royal Infirmary but he joined the Royal Army Medical Corps in 1942.
On June 7 1944, with the 5th Battalion of the Cameron Highlanders, he landed in Normandy.
A week later, at the battle of Sainte Honorine, he was awarded the Military Cross for his outstanding bravery, tending the wounded under heavy fire.
After the war he decided to go into general practice. In 1948 he became the partner of the late Jack Swanson in Aberfeldy.
Mr Yellowlees was to remain as a family doctor for 33 years until his retirement in 1981.
In 1950 he married Sonia Doggart and together they had three children Robin, Mike and Jane. Sonia died in 2003.
Among Mr Yellowlees’ achievements were the establishment of the Robert McCarrison Society and the Royal College of General Practitioners.
He is survived by his children and five grand-children Catherine, Michael, Jamie, Kate and Kirsty. The funeral is at the Church of Scotland, Aberfeldy, on Wednesday at midday.
