BRITAIN’S most decorated female Olympic athlete of all time and the man who invented the forerunner of today’s dialysis machine are in the running to be named Greatest Glaswegian.

But will you vote rower Katherine Grainger or chemist Thomas Graham as your number one?

Over the summer we are revealing the names of 100 men and women who have put the city on the map through sport, science, politics, the arts and more.

Most were born here, some moved here to work or study and have since made the city their own, opening the eyes of others around the world to its strengths and successes; and others have made such an impact on Glasgow that, despite having been born elsewhere, they are inextricably linked with the city, its people, culture and ideals.

Once all 100 have been announced, we will be opening our list up to a public vote, giving our readers the chance to determine who should be crowned Greatest Glaswegian.

Katherine Grainger won gold at the London 2012 Olympics, and silvers at Sydney, Athens, Beijing and Rio, making her the first British woman to win medals at five successive Olympic Games.

She was born and grew up in Glasgow, the daughter of teachers, and she studied at both Glasgow and Edinburgh Universities.

It was while at university that Katherine took up rowing, and she won her first international gold medal at the U23 World Rowing Championships.

In 2012, to mark the golden jubilee of the Evening Times Scotswoman of the Year award, she was presented with the Editor’s Trophy in recognition of her incredible achievements and inspirational legacy. She was made a Dame in the 2017 New Years Honours List for services to rowing and charity.

There is a statue of Glasgow-born scientist Thomas Graham in George Square, and Strathclyde University has named one of its buildings after him, but many people may not be aware of the extent of his achievements.

Born in the city in 1805, Thomas joined Anderson’s Institution (now the University of Strathclyde) as a Professor of Chemistry in 1830. Three years later, he published On the Law of the Diffusion of Gases, a groundbreaking work which cemented his international reputation and became known as Graham’s Law.

After a move to London, he became Professor of Chemistry at the recently-founded University College and by 1844 he was recognised as the leading chemist in England.

In 1861, he invented what he called a ‘dialyzer’ to separate colloids and crystalloids. The method of separation is exactly that used in modern-day dialysis to separate urea from blood in the treatment of kidney disease.
