On November 26th 1836 John McAdam, the inventor of the "tar macadam" road surface, died..
A little known fact is that The McAdams changed their name due to the outlawing of the original family name, if this hadn't happened we may very well have been calling his innovation, Tarmacgregor, which also has a wee ring to it, don't you think? Adam was chosen as they were a religious lot!
John attended Mr. McDoick's school at Maybole, where he is said to have constructed a model of a road, although I can only find this on wiki so don't take it as gospel!
After his father, James died in 1770 he was sent to New York, entering the counting-house of a merchant uncle returning to Scotland with a considerable fortune in 1783, and purchased an estate at Sauchrie, Ayrshire.
Among other public offices he held that of road trustee. The highways of this country were at this time in a very bad condition, and McAdam at once began to consider how to effect reforms. At his own expense he began at Sauchrie, despite much opposition, a series of experiments in road making. In 1798 he moved to Falmouth, where he had received a government appointment, and continued his work there His general conclusion was that roads should be constructed of broken stone. In 1815, having been appointed surveyor-general of the Bristol roads, he was able to put his theories into practice.
In 1819 he published a Practical Essay on the Scientific Repair and Preservation of Roads, followed in 1820 by the Present State of Road-making. As the result of a parliamentary inquiry in 1823 into the whole question of road making, his views were adopted by the public authorities, and in 1827 he was appointed general surveyor of roads. In pursuing his investigations he had travelled over thirty thousand miles of road and expended over £5000.
Parliament reimbursed him for his expenses and gave him a handsome gratuity, but he declined a proffered knighthood. John held valid patents on his method of road building that he had developed, undertaken, and built at his own expense. His methods proved so important that his patents were not protected and enforced by the governments, even in at home. The term "Macadamized Road" long since has died out, but today the term TarMac is still used as a contraction of his process.
Parliament eventually awarded John some payment, but he was never completely compensated for his work or received royalties. Towards the end of his life John was offered knighthood for his work, which he turned down, but deferred it in favour of his son, James.
He died at Moffat, Dumfriesshire, on this day in 1836, hand is buried at Moffat Cemetery, Dumfries and Galloway, next to his grandmother.
