Question: Of the schools Thomas Canning taught at, which is the oldest? Passage 1:After receiving his degree from Eastman, Canning taught music theory and composition at Morningside College (1936–1941) and Indiana University of Pennsylvania (1945–1946). In 1946, he took a position with The Royal Conservatory of Music at the University of Toronto, teaching music theory in the RCM's newly created MBac program for training secondary and elementary school music teachers. Canning was appointed Assistant Professor of Theory at Eastman in 1947 and taught there until 1961, when he left for a year to serve at the University of Hull as a Fulbright professor. In 1963 Canning was hired as an associate professor at the newly opened Creative Arts Center at West Virginia University, receiving promotion to full professor in 1967, retiring in 1977. Canning belonged to the American Composers Alliance, The Hymn Society of America, and Pi Kappa Lambda, and was an honorary member of Phi Mu Alpha Sinfonia.
 Passage 2:The route is described in a series of six sectional leaflets, updated in 2008, which are available from Burnley Tourist Information Centre. The first section begins at the Manchester Road canal bridge (where the Weavers' Triangle Visitor Centre is located), and follows the towpath of the Leeds and Liverpool Canal over the Burnley Embankment to Thompson Park. It then follows the River Brun through Bank Hall Park and past Heasandford House where it joins the route of the Brontë Way out of Burnley, almost to Lea Green Reservoir. It then passes the ruined Extwistle Hall and over the River Don to Queen Street Mill Textile Museum in Harle Syke. The second section crosses Todmorden Road, passing a number of farms and over Thursden brook. It then follows the road up the Thursden valley and crosses into West Yorkshire, descending to Widdop Reservoir. Joining the Mary Towneley Loop section of the Pennine Bridleway at the Gorpe track, it moves back into Lancashire and past Hurstwood Reservoir to the Elizabethan hamlet of Hurstwood.
 Passage 3:In the U.S, his debut film role was in the war film Black Hawk Down (2001), playing Medal of Honor recipient Gary Gordon. He then played Detective John Amsterdam in the short-lived Fox television series New Amsterdam (2008), as well as appearing as Frank Pike in the 2009 Fox television film Virtuality, originally intended as a pilot. He became widely known for his role as Jaime Lannister in the HBO fantasy series Game of Thrones, for which he received Primetime Emmy Award nominations for Outstanding Supporting Actor in a Drama Series in 2018 and 2019. He is a UNDP Goodwill Ambassador, drawing public attention to critical issues such as gender equality and climate change.
