Question: How old was the engineer when his invention was tested for Evel Knievel? Passage 1:Golden turned professional in 1915 and was an assistant pro and later head pro at the Tuxedo Club until 1929 when he took the head job at North Jersey Country Club in Paterson, New Jersey. During his time at the Tuxedo Club, he was a three-time semifinalist in the PGA Championship. In 1922, he lost to Emmet French. In 1926, he dropped a semifinal match to Leo Diegel, and the following year he lost in the semis to Joe Turnesa. Golden remained in Paterson for just a year, leaving for the head professional job at Wee Burn Country Club near Darien, Connecticut. While serving as the pro at Wee Burn, Golden won four consecutive Connecticut Open titles (1932–35), with the 1932, 1933 and 1935 events part of the official PGA schedule. His most lucrative win came in 1931, at the Agua Caliente Open in Mexico. Golden finished regulation tied with George Von Elm at 293. The duo agreed prior to the playoff to split first- and second-prize money, a common practice, with each player pocketing $6,750. Golden went on to win the playoff. Without the agreement, he would have won $10,000.
 Passage 2:Margaret Brady was born on 12 February 1857 in Dublin and was baptised in St. Lawrence O'Toole's parish. At that time, her parents were living at 1, Clarence Street. Her father was Patrick Brady, a coal merchant, whose family were from County Meath and her mother was Brigid Brady (née Savage) of Oldtown, Co. Dublin. Margaret's great grandfather Walter Brady was from Nobber in Meath but was originally a Cavan man by birth. His son Walter, Margaret's grandfather, married Margaret O'Connor and had eight children – Catherine, Phil, Anne, Patrick, Larry, Christie, John and Margaret (Aunt). Patrick Brady, her father, married Brigid Savage, a Fingal woman who was the best step dancer of her day in the North County. Margaret had three known siblings, Walter who died as an infant in 1855, as did Brigid in 1860. Another sister, Catherine, died in 1888 leaving a young family behind. Margaret was educated by the Sisters of St Vincent de Paul. She was employed as a stationery shop assistant where she met her future husband, James Pearse.
 Passage 3:ABC's Wide World of Sports was unwilling to pay the price Knievel wanted for the Snake River Canyon jump, so he hired boxing promoter Bob Arum's company, Top Rank Productions, to put the event on closed-circuit television and broadcast to movie Investors in the event took a substantial loss, including promoter Don E. Branker, as well as Vince McMahon of what was then called the World Wrestling Federation. Arum partnered with Invest West Sports, Shelly Saltman's company, to secure from Invest West Sports two things: first, the necessary financing for the jump, and second, the services of Saltman, long recognized as one of America's premier public relations and promotion men, to do publicity so that Knievel could concentrate on his jumps. Knievel hired subcontractor and aeronautical engineer Doug Malewicki to build him a rocket-powered cycle to jump across the Snake River, and called it the Skycycle X-1. Malwecki's creation was powered by a steam engine built by former Aerojet engineer Robert Truax. On April 15, 1972, the X-1 was launched to test the feasibility of the launching ramp. The decision was then made to have Truax build the Skycycle X-2 and have it take off and fly more like a rocket than a motorcycle.
