An MP wants greater recognition of the achievements of the doctor whose Edinburgh-based team found an effective treatment for tuberculosis (TB).
Sir John Crofton was knighted in 1977
Sir John Crofton, now 93, is credited with helping to save the lives of 10 million people worldwide, yet remains unknown outside medical circles.
He developed a treatment based on the simultaneous use of three antibiotics.
Liberal Democrat MP for Edinburgh West, John Barratt, placed a parliamentary motion calling for greater recognition.
TB or consumption was one of the UK's biggest killers.
Half of all those infected died, and those who survived were separated from their families for months while they recuperated.
Sir John, who was professor of respiratory diseases at the University of Edinburgh from 1952 to 1977, helped develop a treatment that led directly to a massive decline in cases.
He was knighted in 1977 and still campaigns for the eradication of TB in developing nations.
