Pietro Abbati Marescotti (1 September 1768 – 7 May 1842) was an Italian mathematician who taught in Modena.
The Valle Po (Po valley) is a valley of the Cottian Alps in the province of Cuneo, Piedmont, northern Italy.
 It gives rise to the longest river in Italy, the Po, before it enters the Pianura Padana (or Plain of the Po).
 It has a length of some 32 km, from Saluzzo to Crissolo, and is home to the Monviso mountain.
 It is bounded by the Val Pellice, Valle Varaita and the Valle del Guil.
 The head of the valley is located at the Traversette pass ("Colle delle Traversette") (2950 m above sea level).
 The valley descends through the King's plain ("Pian del Re") (2020 m), where the Po river has its source.
The Po Valley, Po Plain, Plain of the Po, or Padan Plain (Italian: "Pianura Padana" ] , or "Val Padana") is a major geographical feature of Italy.
 It extends approximately 650 km in an east-west direction, with an area of 46000 sqkm including its Venetic extension not actually related to the Po river basin; it runs from the Western Alps to the Adriatic Sea.
 The flatlands of Veneto and Friuli are often considered apart since they do not drain into the Po, but they effectively combine into an unbroken plain.
Cremona ]    (Emilian: "Carmona" , Lombard: Cremùna ) is a city and "comune" in northern Italy, situated in Lombardy, on the left bank of the Po River in the middle of the "Pianura Padana" (Po valley).
 It is the capital of the province of Cremona and the seat of the local city and province governments.
 The city of Cremona is especially noted for its musical history and traditions, including some of the earliest and most renowned luthiers, such as Giuseppe Guarneri, Antonio Stradivari, and several members of the Amati family.
The Bianca Modenese or Modenese is a breed of dual-purpose cattle from the Po Valley, in the Emilia Romagna and Lombardy regions of northern Italy.
 It is raised for beef and milk production, but in the past was a triple-purpose breed, used also as a draught animal.
 The name derives from that of the province of Modena, where it is thought to have originated.
 In the nineteenth century it was concentrated in the area of Carpi, and was sometimes known as the Carpigiana.
 It was later distributed through much of the Po Valley, and thus also known as the Bianca della Val Padana.
Jacques de Billy (March 18, 1602 – January 14, 1679) was a French Jesuit mathematician.
 Born in Compiègne, he subsequently entered the Society of Jesus.
 From 1629 to 1630, Billy taught mathematics at the Jesuit College at Pontà Mousson.
 He was still studying theology at this time.
 From 1631 to 1633, Billy taught mathematics at the Jesuit college at Rheims.
 From 1665 to 1668 he was professor of mathematics at the Jesuit college at Dijon.
 One of his pupils there was Jacques Ozanam.
 Billy also taught in Grenoble.
 He also served as rector of a number of Jesuit Colleges in Châlons-en-Champagne, Langres and in Sens.
The I.W.P. Buchanan House is a historic house in Lebanon, Tennessee, U.S..
 It was built circa 1894 for Isaac William Pleasant Buchanan, whose father, Dr. Andrew H. Buchanan, was the chair of the Department of Mathematics at Cumberland University.
 Buchanan himself taught Mathematics at Lincoln College in Illinois and co-founded the Castle Heights Military Academy in Lebanon, where he also taught Mathematics.
 The house was designed by architect George Franklin Barber in the Queen Anne style.
 It has been listed on the National Register of Historic Places since January 8, 1979.
Modena (] ; Etruscan: "Mutna"; ; Modenese: "Mòdna") is a city and "comune" (municipality) on the south side of the Po Valley, in the Province of Modena in the Emilia-Romagna region of northern Italy.
Joel Cunningham was the fifteenth vice chancellor of the University of the South and the former president of Susquehanna University.
 He grew up in Oak Ridge, Tennessee and graduated summa cum laude from the University of Chattanooga in 1965 with majors in mathematics and psychology and completed his master's and doctoral degrees in mathematics from the University of Oregon.
 Cunningham is a member of the Sigma Chi Fraternity.
 He began his career in academe as a member of the faculty at the University of Kentucky, where he taught mathematics for five years.
 He made his first return to Tennessee, to his alma mater, in fact, when he was appointed dean of continuing education and mathematics faculty member at the University of Tennessee at Chattanooga, in 1974.
 He served a year as an American Council on Education Fellow with the Chancellor of the University of Tennessee, Knoxville, and the President of the University of Tennessee.
 He left Chattanooga in 1979 to become vice president for academic affairs, dean of the faculty, and professor of mathematics at Susquehanna University in Pennsylvania.
 In 1984 he was named president there where he remained until 2000, when he was elected vice chancellor by Sewanee's board of trustees and made his second Tennessee homecoming.
 He served in this position until 2010.
The M. Gweneth Humphreys Award or Humphreys Award is a mathematics award established by the Association for Women in Mathematics in recognition of mathematics educators who have exhibited outstanding mentorship.
 The award is named for M. Gweneth Humphreys (1911-2006) who earned her Ph.D. at age 23 from the University of Chicago in 1935.
 She taught mathematics to women for her entire career, first at Mount St. Scholastica College, then for several years at Sophie Newcomb College, and finally for over thirty years at Randolph Macon Woman's College.
 This award, funded by contributions from her former students and colleagues at Randolph-Macon Woman's College, recognizes her commitment to and her profound influence on undergraduate students of mathematics.
