Dr June McCarroll: The rebel doctor armed with a paintbrush who defined our roads


Ever wondered where road markings came from? Wonder no more.
It’s the early days of the 20th century. The motor car is still a relatively new invention. Roads are rudimentary, despite sealed tar-paved roads first making an appearance in the Middle East in the 8th Century.
Roads continued to evolve over the centuries, but it was the advent of the motor car that saw a rapid rise in development and construction. Sealing the surface became commonplace, once British engineer Edgar Purnell Hooley patented his idea for tarmac in 1901.
While John Loudon McAdam invented the method of road surfacing that would become known as macadam, it was Hooley who added tar to the macadam aggregate mixture to create tarmac, the process creating a smooth surface and with reduced levels of dust and detritus.

National Inventors' Day: Ayrshire's brightest minds remembered


1. Alexander Fleming
Born in 1881 in Darvel, Sir Alexander Fleming is the man who discovered penicillin – the world’s first effective antibiotic - and in the process saved millions of lives across the world.
Already known as a brilliant researcher, he found cultures of bacteria left in his lab to have been contaminated by a fungus…. which was destroying them. That was penicillin. He shared the Nobel Prize for Medicine in 1945 and was recently voted the Third Greatest Scot, behind Robert The Bruce and William Wallace.
2. John Dunlop
John Boyd Dunlop, born in Dreghorn in 1840, invented the pneumatic tyre. An inventor and vet, he came up with the first inflatable tyre for his son’s bicycle in Ireland in 1997 and revolutionised transport in the process. It was soon used for cycle racing and within years, Dunlop tyres made their name around the world. ....
