input: In 1962 Thompson entered three John Crosthwaite designed cars in the Indianapolis 500. Unusually, they used a stock V8 Buick engine and it was in the rear unlike the front engined, race tuned, Offenhauser powered cars used by most competitors. It was the first stock engine to be raced at Indy since 1946. Thompson's crew, led by Fritz Voigt, were young, smart and hard working. Working 12-14 hour days, the car was designed and built in 120 days. For the race, the engine (enlarged to 4.2 litre capacity, the maximum allowed by the regulations for "stock block" engines) had to be detuned because they were concerned it would not last the distance. Despite being more than 70 bhp down on the other cars, Dan Gurney qualified eighth and was in ninth place until a leaking oil seal seized the gearbox and ended his race on lap 94. He was placed 20th out of 33. The team won the Mechanical Achievement Award for original design, construction and accomplishment. Thompson's promotion skills pleased the sponsors with the publicity generated that year. For the 1963 Indianapolis 500 Crosthwaite designed the innovative Harvey Aluminium Special "roller skate car" with the then pioneering smaller profile (12 inch diameter) and wide racing tires (front 7 inches and rear 9 inches wide) and wheels. Thompson took five cars to Indianapolis. Two of the previous year's design with Chevrolet V8 engines and three roller skate cars. One of the new cars, the Harvey Titanium Special, featured a lightweight titanium chassis. Al Miller II raced one of the modified 1962 cars to ninth place despite only qualifying in 31st position. Duane Carter qualified one of the roller skate cars 15th but was only placed 23rd after an engine failure on the 100th lap. The small tire sizes and low car weights caused complaints amongst the old hands and owners, so for future races, cars were restricted to minimum tire sizes and minimum car weights. 1962 Formula One World Champion Graham Hill tested one of the roller skate cars at Indianapolis in 1963, but refused to race it citing its poor handling. In 1963 Thompson traveled to England where, along with Dante Duce, he demonstrated his Ford-powered top fuel Harvey Aluminum Special dragster at the Brighton Speed Trials. It was then displayed at the Racing Car Show in London in January 1964. Thompson brought three modified 12-inch tire cars to the 1964 Indianapolis 500, but new rules required him to use 15-inch tires. The Allstate sponsored team used Allstate tires and Ford engines. The chassis had to be altered to accommodate the larger Ford engines. Two of them qualified for the race. The car No.84 began the month with Masten Gregory as the driver but Eddie Johnson in car No.84 qualified 24th and finished 26th. Dave MacDonald in car No.83 qualified 14th and died in a fiery crash on the second lap.

input: The elder Boulton's business prospered after young Matthew's birth, and the family moved to the Snow Hill area of Birmingham, then a well-to-do neighbourhood of new houses. As the local grammar school was in disrepair Boulton was sent to an academy in Deritend, on the other side of Birmingham. At the age of 15 he left school, and by 17 he had invented a technique for inlaying enamels in buckles that proved so popular that the buckles were exported to France, then reimported to Britain and billed as the latest French developments. On 3 March 1749 Boulton married Mary Robinson, a distant cousin and the daughter of a successful mercer, and wealthy in her own right. They lived briefly with the bride's mother in Lichfield, and then moved to Birmingham, where the elder Matthew Boulton made his son a partner at the age of 21. Though the son signed business letters "from father and self", by the mid-1750s he was effectively running the business. The elder Boulton retired in 1757 and died in 1759. The Boultons had three daughters in the early 1750s, but all died in infancy. Mary Boulton's health deteriorated, and she died in August 1759. Not long after her death Boulton began to woo her sister Anne. Marriage with a deceased wife's sister was forbidden by ecclesiastical law, though permitted by common law. Nonetheless, they married on 25 June 1760 at St. Mary's Church, Rotherhithe. Eric Delieb, who wrote a book on Boulton's silver, with a biographical sketch, suggests that the marriage celebrant, Rev. James Penfold, an impoverished curate, was probably bribed. Boulton later advised another man who was seeking to wed his late wife's sister: "I advise you to say nothing of your intentions but to go quickly and snugly to Scotland or some obscure corner of London, suppose Wapping, and there take lodgings to make yourself a parishioner. When the month is expired and the Law fulfilled, live and be happy ... I recommend silence, secrecy, and Scotland." The union was opposed by Anne's brother Luke, who feared Boulton would control (and possibly dissipate) much of the Robinson family fortune. In 1764 Luke Robinson died, and his estate passed to his sister Anne and thus into Matthew Boulton's control. The Boultons had two children, Matthew Robinson Boulton and Anne Boulton. Matthew Robinson in turn had six children with two wives. His eldest son Matthew Piers Watt Boulton, broadly educated and also a man of science, gained some fame posthumously for his invention of the important aeronautical flight control, the aileron. As his father before him, he also had two wives and six children.
