	==Biography==		==Biography==
	===Family and Early Life===		===Family and Early Life===
			Bernard (Ben) Etkin was born in Toronto, Ontario, on May 7, 1918. Bernard Etkin was their only son and youngest of five children. His parents Samuel and Mary were poor Jewish immigrants from Belarus, and ran a small cleaning and tailoring business until it ran into trouble during the Depression. When the Etkins lost their family business, Ben, as he was known, quit high school to work at [http://en.wikipedia.org/wiki/Philco Philco] assembling radios in order to support the family. He eventually completed high school through part time evening classes.<ref name=stoffman/><ref name=haim/>

	===Education===		===Education===
			After graduating from high school, he enrolled as a part time student at the University of Toronto Faculty of Applied Science and Engineering, with his tuition paid for in part by his working sisters. He eventually enrolled full time and completed his degree in [[Engineering Physics]] in 1941. Following his graduation, Etkin joined the University of Toronto Department of Civil Engineering (which then housed the fledgling aeronautics researchers) as a graduate student and lecturer, finishing his Master's degree in 1943.<ref name=stoffman/><ref name=white/>

	===Professor at UTIAS===		===Professor at UTIAS===
			When the Department of Aeronautics was created in 1946, Etkin was appointed as one of its first two faculty members (along with [[T.R. Loudon]]). He helped found the [[University of Toronto Institute of Aerophysics]] (later renamed University of Toronto Institute for Aerospace Studies, UTIAS) along with [[Gordon Patterson]] in 1949.<ref name=white/>

			As a member of UTIAS, Etkin continued to teach, but also conducted groundbreaking research into various areas of aeronautics. His research on aerodynamic theory led to 11 patents and three books on flight dynamics, including the seminal text ''Dynamics of Flight: Stability and Control''.<ref name=Etkin-Dynamics/><ref name=utmemoriam/>

			Etkin was involved in the design, production, and testing of 10 planes and two gliders during his time as a professor. His work included contributions to the [http://en.wikipedia.org/wiki/Avro_Canada_CF-105_Arrow Avro Arrow] (for which he conducted research into wing aerodynamics) and the [http://en.wikipedia.org/wiki/Czerwi%C5%84ski_Sparrow de Havilland "Sparrow" glider].<ref name=utmemoriam/>

			Etkin also designed and built a large wind tunnel at UTIAS to test the effects of wind on buildings and aircraft. He consulted on the construction of Toronto City Hall in the 1960s.<ref name=stoffman/> He also invented the "infrasizer", an apparatus like a wind tunnel which sorted particles based on weight and resistance to airflow, of critical importance to aerospace studies.<ref name=utmemoriam/>

			In addition to research, Etkin was known for his teaching. He taught over thirty different courses during his time as a professor, including both advanced aerospace courses and first year courses in mechanics.<ref name=utmemoriam/>

	====Apollo 13====		====Apollo 13====
			On April 16, 1970, as the [http://en.wikipedia.org/wiki/Apollo_13 Apollo 13] NASA mission was in the midst of its troubled flight, Etkin and his colleagues received a call from Grumman Aerospace, the contractor responsible for the Lunar Modules on the Apollo landers. Grumman required the help of Etkin and five other engineers from UTIAS to solve the problem of how to safely separate the Lunar Module (LM) from the Command Module (CM) before re-entry.

			During normal operation, the LM would have been separated from the CM prior to lunar landing using the Service Module's reaction control system (RCS). On Apollo 13, however, the RCS was inoperative because of the power failure caused by an earlier explosion in an oxygen tank in the Service Module. Re-entry into Earth's atmosphere with the LM attached was not an option, nor was a simple decoupling, since the LM was likely to tumble into the path of the CM as it entered the atmosphere.

			Etkin's team, which included Barry French, Philip Sullivan, Peter Hughes, Irvine Glass, and Rod Tennyson, had only 6 hours to solve this problem, as the astronauts were running low on air and supplies in the last stages of its flight. Etkin's team concluded that pressurization of the airlocked tunnel between the LM and the CM would allow the LM to detach. However, the pressure had to be precisely calculated. If the pressure was too high, the tunnel hatch may be damaged; if too low, the LM would not safely separate.<ref name=stoffman/>

			Using only slide rules, the team came up with a figure - two pounds per square inch - that would safely decouple the LM and the CM. This figure was relayed to Grumman, and was successfully used by NASA to save the Apollo 13 astronauts. Computer simulations conducted thirty years later verified the accuracy of the UTIAS numbers.<ref name=haim/>

			The team was honoured for their work in a ceremony at the Canadian Air and Space Museum in 2010.<ref>http://www.thestar.com/news/gta/2010/04/13/u_of_t_engineers_recognized_for_apollo_13_rescue.html</ref>
