Alvin "Al" Goldfarb was the tenth president of Western Illinois University.  Prior to his current position from 1977 to 2002 he was on the faculty of the department of theatre at Illinois State University in Normal, where he was also chairman of the theatre department, dean of fine arts from 1988 to 1998, and provost and vice president for academic affairs from 1998.  He earned a Ph.D. in theater history from the City University of New York.  In 2006 Goldfarb announced that he was being treated for prostate cancer and that a complete recovery was expected.  At the July 2009 meeting of the WIU Board of Trustees, Goldfarb officially announced his intention to retire on June 30, 2011.  It was announced that President Goldfarb would be succeeded as president of the university by Western's current Provost and Vice President for Academic Affairs, Dr. Jack Thomas, who succeeded him on July 1, 2011.  A search committee will now search for an Interim Provost, as well as for two other Vice President positions whose present incumbent officeholders will be retiring soon.  President Goldfarb's and incoming President Thomas's principal priority, besides having a seamless transition and a quick search for candidates, is to deal with the fact that the University is owed more than $50 million by the government of the State of Illinois, and must find further non-critical areas to hone and look to alternative sources of funding like non-government grants and loans, private donations and gifts, and to alumni. Samuel Henry Harkwood (Sam) Livingston (4 February 1831 – 4 October 1897) originally born in Ireland, he came to Canada following an unsuccessful venture in the Californian gold rush of 1849, and eventually found his way to Jumping Pound, North-West Territories, in 1873 where he opened a trading post.  He was going to settle near the confluence of the Bow and Elbow Rivers in 1875 but, when the North-West Mounted Police arrived and established Fort Calgary, Livingston and his family moved further up the Elbow River to the current location of the Glenmore Reservoir.  When the Glenmore Dam was built and the area flooded, part of the Livingston house was preserved and now stands at Heritage Park.  Sam Livingston was an important man to Alberta's history.  The Glenmore Reservoir gets its name from Sam too; Sam and Jane started a school on their farm that Sam named 'Glenmore School' after a place in Ireland.  Glenmore is a village in County Kilkenny and quite close to his birthplace in County Wicklow. Sir Henry Morton Stanley, GCB (born John Rowlands; 28 January 1841 – 10 May 1904) was a Welsh-American journalist and explorer who was famous for his exploration of central Africa and his search for missionary and explorer David Livingstone.  Upon finding Livingstone, Stanley reportedly asked, "Dr. Livingstone, I presume?"  Stanley is also known for his search for the source of the Nile, his work in and development of the Congo Basin region in association with King Leopold II of Belgium, and commanding the Emin Pasha Relief Expedition.  He was knighted in 1899. In combinatorial game theory, the Sprague–Grundy theorem states that every impartial game under the normal play convention is equivalent to a nimber.  The Grundy value or nim-value of an impartial game is then defined as the unique nimber that the game is equivalent to.  In the case of a game whose positions (or summands of positions) are indexed by the natural numbers (for example the possible heap sizes in nim-like games), the sequence of nimbers for successive heap sizes is called the nim-sequence of the game. Mega Man 2, known in Japan as Rockman 2: Dr. Wily no Nazo (ロックマン2 Dr.ワイリーの謎 , Rokkuman 2 Dr. Wairī no Nazo , "Rockman 2: The Mystery of Dr. Wily") , is an action-platform game developed and published by Capcom for the Nintendo Entertainment System.  It is the second installment in the original "Mega Man" series.  The game was released in Japan 1988 and in North America and PAL regions the following years.  "Mega Man 2" continues the titular protagonist's battle against the evil Dr. Wily and his rogue robots.  The game features graphical and gameplay changes from the first "Mega Man" game, many of which have remained throughout the series. Stanley and the Search for Dr. Livingston (after "David Livingstone") is a side-scrolling action-adventure game for the Nintendo Entertainment System that appeared in one of the first 50 issues of Nintendo Power magazine. David M. Livingston is the Deputy Director of the Dana-Farber/Harvard Cancer Center, Emil Frei Professor of Genetics and Medicine at Harvard Medical School, Chairman of the Executive Committee for Research at Dana-Farber Cancer Institute.  Dr. Livingston joined the Harvard faculty in 1973.  His research focuses on breast and ovarian cancer. His fame as an explorer and his obsession with discovering the sources of the Nile River was founded on the belief that if he could solve that age-old mystery, his fame would give him the influence to end the East African Arab-Swahili slave trade.  "The Nile sources," he told a friend, "are valuable only as a means of opening my mouth with power among men.  It is this power which I hope to remedy an immense evil."  His subsequent exploration of the central African watershed was the culmination of the classic period of European geographical discovery and colonial penetration of Africa.  At the same time, his missionary travels, "disappearance", and eventual death in Africaand subsequent glorification as a posthumous national hero in 1874led to the founding of several major central African Christian missionary initiatives carried forward in the era of the European "Scramble for Africa".
