Gerald Vincent Bull (March 9, 1928 – March 22, 1990) was a Canadian engineer who developed long-range artillery. Bull moved from project to project in his quest to economically launch a satellite using a huge artillery piece, to which end he designed the Project Babylon "supergun" for Saddam Hussein's government in Iraq.
On March 22, 1990, he was shot dead outside his apartment in Brussels, Belgium. His assassination is believed to be the work of Israel's Mossad over his work for the Iraqi government. No person has ever been charged with his murder.
Early life Gerald Vincent Bull was born on March 9, 1928 in North Bay, Ontario, Canada. He is the son of George L. Toussaint Bull, a solicitor, and Gertrude Isabelle (née LaBrosse) Bull. George Bull was from a family from the Trenton area and had moved to North Bay in 1903 to start a law firm. As a Roman Catholic, LaBrosse would have been forbidden from marrying Bull, an Anglican. George converted to Roman Catholicism on February 20, 1909, and the couple married three days later. They would go on to have 10 children.
George Bull was offered the position of King's Counsel in 1928. The family was well off, but the Wall Street crash of 1929 and ensuing Great Depression dramatically changed their circumstances. Within a year the loans Bull had taken to buy stocks on margin were called in, and the family was forced to move to Toronto to look for work.
The next year Gertrude Bull suffered complications while giving birth to her 10th child, Gordon. She died April 1, 1931. George Bull suffered a nervous breakdown and fell into heavy drinking; he left his children in the care of his sister Laura, who fell victim to cancer and died in mid-1934. The next year, banks foreclosed on the family home. The same year, George, at the age of 58, met and married Rose Bleeker. He gave up the children to various relatives: Gerald ending up living with his older sister Bernice.
In 1938, Gerald was sent to spend the summer holidays with his uncle and aunt, Philip and Edith LaBrosse (Philip was the younger brother of Gerald's mother, Gertrude). During the Depression, Phil and Edith had won about $175,000 in the Irish Sweepstakes, and were relatively well off. Gerald was sent to an all-boys Jesuit school, Regiopolis College, Kingston, Ontario. Although too young to attend, the school allowed him to start in 1938 and he returned to spend the summers with the LaBrosses. During this time he took up the hobby of building balsa wood airplanes of his own design, and was a member of the school's modelling club. He graduated in 1944.
University
After graduating, Bull entered Queen's University, with hopes of eventually entering military officers' training school. Philip LaBrosse visited the University of Toronto (U of T) with the intention of having Bull placed there. He wrote to Bull, who was in Kingston, having found room in the medical school. Bull declined the offer and instead asked LaBrosse if a position in the new aeronautical engineering course was available. The department, being brand new, had limited qualifying criteria for entrance and agreed to interview Bull even though he was only sixteen years old – and he was accepted into the undergraduate program. Records and recollections of both classmates and his professors show little evidence of Bull's brilliance; one professor noted that "He certainly didn't stand out". After graduating in 1948, with marks that were described as "strictly average", Bull took a drafting job at A.V. Roe Canada.
Later that year, the University of Toronto opened a new Institute of Aerodynamics (now the Institute for Aerospace Studies) under the direction of Dr. Gordon Patterson. The Institute could afford to employ twelve students, accepting three per year for a four-year period, and was funded by the Defence Research Board (DRB). Bull applied and was accepted at Patterson's personal recommendation, as Patterson felt that any lack in academics was made up for by Bull's tremendous energy. Bull was soon assigned to work with fellow student Doug Henshaw, and the two were given the task of building a supersonic wind tunnel, which was at that time a relatively rare device.
When the Royal Canadian Air Force donated land adjacent to RCAF Station Downsview to the institute, the operations were quickly moved. During construction, Bull used the wind tunnel as the basis for his September 15, 1949 Master's thesis, on the design and construction of advanced wind tunnels. The tunnel was to be featured prominently during the opening of the new Institute grounds, leading to an all-night rush to get it fully operational in time for the presentation. The work was completed at 3:30 am, but the team was too exhausted to test it. The next day Air Marshal Wilfred Curtis pushed the start button and nothing happened, but Dr. Patterson quickly reached around, pushed harder, and the wind tunnel worked perfectly.
Bull had largely finished his PhD thesis on the same topic in 1950, when a request from the DRB asking that the Institute provide an aerodynamicist to help on their Velvet Glove Missile project arrived. It was to be an unpaid position on which the volunteer would remain on a normal PhD stipend from the university. Patterson selected Bull for the position, which led to a period of successful work at the Canadian Armament and Research Development Establishment, or CARDE.
Career
Canada The Canadian Armament and Research Development Establishment (CARDE) was formed as a joint Canadian-British operation to study artillery and ballistics, in an effort to harness the intellectual resources of Canada, as well as to place developing British technology outside of German reach during World War II. Formed up on a military training area and artillery range outside Valcartier, northwest of Quebec City, CARDE was one of a number of research divisions of the DRB that were well funded in the immediate post-war era. CARDE was researching supersonic flight and a variety of rocket and missile projects when Bull was asked to join. Bull asked to build a wind tunnel for this research, but his suggestions were dismissed as too expensive.
Gunners at CARDE suggested that firing models out of existing gun barrels would permit gathering data at much lower cost, and guided Bull in this direction. As a proof of concept, they tried an Ordnance QF 17-pounder barrel bored to . The aerodynamicists' demands to accommodate larger models resulted in boring out a BL 5.5 inch Medium Gun barrel to produce a smooth-bore. Borrowing an idea developed in England in 1916, cards were placed on holders along the range and scaled models of the missile fired through them. The models were carried in a segmented aluminum sabot, which peeled away as the round left the muzzle.
As originally built the range was long, with "jump cards" located at intervals. A metallic coating on the cards permitted timing of flight progress to measure velocity. One station was equipped for Schlieren photography to record the shock waves and wake around the projectile. In some ways this technique was superior to wind tunnel study, as it allowed for the direct measurement of real-world influences on the trajectory, as a test of theoretical calculations. On the downside, reducing the collected data to a mathematical trajectory for checking against the theoretical calculations is difficult.
Bull was at CARDE briefly before returning to the university to defend his thesis in March 1951, at 23 years old becoming the youngest PhD graduate in the institute's history—a record that remains to this day. He returned to CARDE, now on the DRB's payroll, and continued working on the instrumented guns. On one of these trips, in 1953, he and a friend stopped in Charny after a fishing trip to drop off some of their catch at a local doctor's house. Bull met Noemi "Mimi" Gilbert, the doctor's daughter, and the two soon started dating. Given Bull's work schedule they were rarely able to see each other, but they became engaged in February 1954, and married on July 15. Gilbert gave the couple a small house as a wedding gift. Mimi gave birth to their first son, Phillippe, on July 3, 1955, and a second, Michel, in November 1956.
In 1954 Bull decided that a wind tunnel was too important to ignore, even if he could not arrange for funding through the DRB. Instead, he gained the ear of professors at Laval University in Quebec City, and Bull and a number of graduate students started work on a tunnel similar to the one he had earlier built at U of T. It opened in the summer of 1955 and was capable of speeds up to Mach 4, but cost only $6,000, the result of using scrap for most of its parts.
Bull's work was brought to the public's attention in a May 20, 1955 Toronto Telegram headline article, Unveil Canadian Gun that Fires 4,550 M.P.H. Missiles. Around this time Bull further improved the data-collection capabilities of the system by developing a telemetry system that could fit in the models. DRB staff thought the idea was unworkable and worked against having it funded, but Bull shuffled his own department's funding and went ahead and developed it anyway. All the parts of Bull's future efforts, smooth-bore high-velocity guns, sabots for increasing performance, and hardened electronics, were now complete.
Work on the Velvet Glove ended in 1956, and the DRB turned its attention to anti-ballistic missiles (ABMs). Bull's gun system was not fast enough to be useful in this role, so it was adapted to use a "sabot" to improve its performance. Bull then moved on to hypersonics research and the study of infrared and radar cross sections for detection. As the UK's research efforts wound down in the post-war political environment, CARDE's joint UK-Canadian funding was dramatically cut back, with the project eventually being handed over to the Canadians entirely and followed by further cuts. Bull was vocal about this turn of events, calling the Liberal government of the day "second-rate lawyers and jumped-up real-estate salesmen".
During this period CARDE was visited by a US team, including Lieutenant General Arthur Trudeau, who was impressed with Bull's work. Trudeau was director of US Army Research and Development, and he quickly set up a similar effort at the Aberdeen Proving Ground under the direction of Dr. Charles Murphy. They built an analog of Bull's gun using a gun and started test firing it over the Atlantic in 1961. The team used a fire-control radar from a Nike Hercules missile battery to track the shells, which released a cloud of chaff at altitudes up to .
Around the same time, Bull and Murphy started discussing the idea of firing scale aircraft models from their guns. Both started working on the idea, but Bull beat Murphy when he successfully fired a model of the Gloster Javelin from his gun and managed to take shadowgraph photos of it showing supersonic shock cones. Bull then used the same method to work on the Avro Arrow, discovering an instability that led to the use of a stability augmentation system. Work on the Avro Arrow was soon cancelled, which angered Bull.
With attention turning to space after the launch of Sputnik in 1957, Bull leaked a story that Canada would soon match this feat by placing a high-velocity gun in the nose of a US Army Redstone missile. The story was a complete fabrication, but caused a major stir when it hit the papers on April 22, 1958. After the story broke Prime Minister John Diefenbaker was besieged in the House of Commons press scrum, later dismissing it stating that "There is no foundation whatsoever to the story, not a scintilla of truth to it".
