A major historical figure will be honoured for his contributions to medicine.
A pioneering Aberdeen medic is to be honoured with a commemorative plaque on Union Street.
Sir Alexander Ogston, who lived between 1844 and 1929, was a professor of surgery.
The surgeon was known to have lived at the site of number 252 on the busy city centre.
In 1881, while working in his home laboratory, he discovered the Staphylococcus organism and showed it to be the main cause of post-operative wound infection.
He was an advocate for antiseptic surgery and while serving in the military he championed the creation of the Royal Army Medical Corp as well as introducing new procedures at Aberdeen Royal Infirmary.
Ogston began his medical training at Marischal College in 1862 and graduated in 1865. After receiving a request from the Aberdeen Medico-Chirurgical Society, the Aberdeen City Council’s City growth and resources committee approved the plaque.
The Aberdonian surgeon will also be celebrated at a new visitor attraction at Provost Skene’s House.
The historical building, which is being redeveloped by the council, is gearing up to showcase local people who transformed the world.
