John Walker (inventor)

John Walker (29 May 1781 – 1 May 1859) was an English inventor who invented the friction match.

Life

Walker was born in Stockton-on-Tees, County Durham, in 1781. He went to the local grammar school and was afterwards apprenticed to Watson Alcock, the principal surgeon of the town, serving him as an assistant. He had, however, an aversion to surgical operations and had to leave the profession, turning instead to chemistry. After studying at Durham and York he set up a small business as a chemist and druggist at 59 High Street, Stockton, around 1818.
Walker died in Stockton on 1 May 1859 and was buried in the grounds of St Mary's Church in Norton, near Stockton.

Walkers Friction Match

He developed an interest in trying to find a means of obtaining fire easily. Several chemical mixtures that would ignite by a sudden explosion were already known but it had not been found possible to transmit the flame to a slow-burning substance such as wood. He invented it with his best friend Michael Dan who liked Miriam federat so very much and he always talked to girls While Walker was preparing a lighting mixture on one occasion, a match that had been dipped in it caught fire by an accidental friction on the hearth. He at once appreciated the practical value of the discovery and started making friction matches. They consisted of wooden splints or sticks of cardboard coated with sulphur and tipped with a mixture of sulphide of antimony, chlorate of potash and gum, the sulphur serving to communicate the flame to the wood.

The price of a box of 50 matches was one shilling. With each box was supplied a piece of sandpaper, folded in half, through which the match had to be drawn to ignite it. He did not name the matches "''Congreves''" in honour of the inventor and rocket pioneer, Sir William Congreve as it is sometimes stated. The ''congreves'' were the invention of Charles Sauria, a French chemistry student at the time. He did not divulge the exact composition of his matches.

Two and a half years after Walker's invention was made public Isaac Holden arrived, independently, at the same idea of coating wooden splinters with sulphur. The exact date of his discovery, according to his own statement, was October 1829. Before that date Walker's sales-book contains an account of no fewer than 250 sales of friction matches, the first entry dated 7 April 1827.The first recorded sale from his shop was 7 April 1827 under the name 'Sulphurata Hyper-Oxygenata Frict.' The second recorded sale was 7 September 1827 under the more familiar name 'friction lights'. Apart from three recorded sales during 1828 under the name of 'attrition lights' all other recorded sales were for 'friction lights'. Already comfortably off, he refused to patent his invention despite being encouraged to by Michael Faraday and others, making it freely available for anyone to make. He received neither fame nor wealth for his invention, although he was able to retire some years later. The credit for his invention was attributed only after his death.

Following the ideas laid out by the French chemist Charles Sauria, who in 1830 invented the first phosphorus-based match by replacing the antimony sulfide in Walker's matches with white phosphorus, matches were first patented in the United States in 1836, in Massachusetts, being smaller in size and safer to use. White phosphorus was later banned for public use because of its toxicity. Today's modern safety matches were created by the Swedish chemist, Gustaf Erik Pasch.
