THE CALCULATING BOY
An elder brother had taught him to count to one hundred. His great haunt was the forge of the village blacksmith, a kindly old man, about whom more presently. In his workshop neighbours would gather to prove the boy with hard questions involving figures, as it soon became known that he had an extraordinary faculty for calculation. The earliest public notice of this that has been met with is in a letter dated January 19th, 1814, and signed "I. Isaac," printed in the Monthly Magazine (xxxvii. 104).
"Sir,—Having heard that George Parker Bidder, seven years of age," (he was really seven months over the seven years, as he was born June 14th, 1806) "has a peculiar talent for combining numbers, I sent for him, desired him to read a few verses of the New Testament, and found he could scarcely do it even by spelling many words; and knew not the numbers of the letters from one to ten." (Mr. Isaac then asked him several questions in the first four rules of arithmetic, to each of which he replied correctly and readily. He then proceeds to say): "I then asked him how many days are in two years. But here he was at a stand, did not know what a year is, or how many hours are in a day, but having the terms explained, he soon made out the hours in a week, in a month, in twelve months. When asked how many inches are in a square foot, he soon signified that he knew neither of the terms, nor how many inches a foot contains, but with the aid of explanation he soon made out the number 1728; and when desired to multiply this by twelve, he complained the number was too large, but having time, about two minutes, he made out the number 20,738."
His father now took him over the country to exhibit his wonderful powers. In 1815 he was presented to Queen Charlotte. He is said to have been a singularly bright and prepossessing boy. In a memoir in the Proceedings of the Institute of Civil Engineers (lvii. pp. 294) we read:—
"Travelling about the country, for the purpose of exhibiting his son's powers, proved so agreeable and profitable to his father, that the boy's education was entirely neglected. Fortunately, however, amongst those who witnessed his public performances were some gentlemen who thought they discerned qualities worthy of a better career than that of a mere arithmetical prodigy. The Rev. Thomas Jephson and the late Sir John Herschel visited Moreton in the autumn of 1817, to see the 'Calculating Boy,' and they were so much impressed by his talent and general intelligence that before the vacation was over Mr. Jephson and his Cambridge friends agreed to defray the expenses of his education, and he was placed with the master of the grammar school at Camberwell. There he remained for about a twelvemonth, when his father insisted on removing him, for the purpose of resuming the exhibition of his talents. Among other places, he was taken to Edinburgh, where he attracted the notice of Sir Henry Jardine, who, with the assistance of some friends, became responsible for his education. Bidder was then placed with a private tutor, and afterwards, in 1819, he attended the classes at the University of Edinburgh."
He quitted Edinburgh in 1824, and was given a post in the Ordnance Survey. In April, 1825, he quitted the Ordnance Survey and was engaged as assistant to Mr. H. R. Palmer, a civil engineer.
It is deserving of remembrance that George Bidder's first care when starting in the world was to provide for the education of his two younger brothers, and for that purpose this lad of eighteen stinted and saved, denying himself all but the barest necessities.
In 1833 he superintended the construction of the Blackwall Wharf, and in 1834 joined George and Robert Stephenson, whom he had known in Edinburgh.
Experience showed him the importance of electric communication between stations; he introduced it on the Blackwall and Yarmouth railways, and became one of the principal founders of the Electric Telegraph Company.
In hydraulic engineering his chief works were the construction of Lowestoft Harbour and the Victoria Docks at North Woolwich.
