Carl Ortwin Sauer (December 24, 1889 – July 18, 1975) was an American geographer. Sauer was a professor of geography at the University of California at Berkeley from 1923 until becoming professor emeritus in 1957 and was instrumental in the early development of the geography graduate school at Berkeley. One of his best known works was Agricultural Origins and Dispersals (1952). In 1927, Carl Sauer wrote the article "Recent Developments in Cultural Geography," which considered how cultural landscapes are made up of "the forms superimposed on the physical landscape."

He was born in Warrenton, Missouri and graduated from the University of Chicago with a Ph.D. in 1915.

Carl Sauer's paper "The Morphology of Landscape" was probably the most influential in developing ideas on cultural landscapes and is still cited today. However, Sauer's paper was really about his own vision for the discipline of geography, which was to establish the discipline on a phenomenological basis, rather than being specifically concerned with cultural landscapes. "Every field of knowledge is characterized by its declared preoccupation with a certain group of phenomena,” according to Sauer. Geography was assigned the study of areal knowledge or landscapes or chorology. “Within each landscape there are phenomena that are not simply there but are either associated or independent of each other.” Sauer saw the geographer’s task as being to discover the areal connection between phenomena. Thus "the task of geography is conceived as the establishment of a critical system which embraces the phenomenology of landscape, in order to grasp in all of its meaning and colour the varied terrestrial scene"

Carlo Ancelotti (Italian pronunciation: [ˈkarlo antʃeˈlɔtti]; born 10 June 1959) is an Italian football manager, and the current manager of Paris Saint-Germain in the French Ligue 1. Nicknamed Carletto, Ancelotti played as a midfielder and had a successful career with Roma – captaining the team – with whom he won one Scudetto and four Coppa Italia honours and was part of the legendary late 1980s Milan team with whom he won two Scudetti and two European Cups in a five-year period. He was capped 26 times and scored one goal for the Italian national team and appeared at the 1986 and 1990 World Cups.

After spells as manager of Reggiana, Parma and Juventus, Ancelotti was appointed Milan manager in 2001. He won the Scudetto in 2004, the Champions League in 2003 and 2007 and the Coppa Italia in 2003. They were also Serie A and Champions League runner-ups in 2005. He is one of six men to have won the European Cup/Champions League as player and manager. In May 2009, he was appointed Chelsea manager and in his first season led them to a historic Premier League and FA Cup Double. He became only the second non-British manager to win the double, the other being Arsène Wenger. After an uneven Premier League season in which Chelsea failed to retain the title, Ancelotti was dismissed as their manager in May 2011. On 30 December 2011, Ancelotti signed a contract with ambitious French side Paris Saint-Germain.

Boris Franz Becker (born 22 November 1967) is a former World No. 1 professional tennis player from Germany. He is a six-time Grand Slam singles champion, an Olympic gold medalist, and the youngest-ever winner of the men's singles title at Wimbledon at the age of 17. Becker also won five major indoor championships titles including three ATP Masters World Tour Finals (played eight finals, second all-time to Ivan Lendl, who played nine) and one WCT Finals and one Grand Slam Cup. He also won five Masters 1000 series titles and eight Championship Series titles. Tennis Magazine put Becker in 18th place on its list of the 40 greatest tennis players from 1965 to 2005.

Becker was born in Leimen, West Germany, the only son of Elvira (née Pisch), who was raised in Czechoslovakia. His parents were Catholic, and part of his mother's family were Jewish. His father Karl-Heinz, an architect, founded the tennis centre (Tennis-Club Blau-Weiß 1964 Leimen e. V.) in Leimen, where Becker learned the game.

Becker turned professional in 1984, under the guidance of Romanian-born coach, Günther Bosch, and with Ion Ţiriac as manager and won his first professional doubles title that year in Munich. As a West German teenager, Becker won his first top-level singles title in June 1985 at Queen's Club and two weeks later on 7 July, became the first unseeded player and the first German to win the Wimbledon singles title, defeating Kevin Curren in four sets. At the time, he was the youngest ever male Grand Slam singles champion at &1000000000000001700000017 years, &10000000000000227000000227 days (a record later broken by Michael Chang in 1989, who won the French Open when he was &1000000000000001700000017 years, &10000000000000110000000110 days). Two months after his triumph, Becker became the youngest winner of the Cincinnati Open.

Thomas Muster (born 2 October 1967 in Leibnitz, Styria) is a former world no. 1 tennis player from Austria. One of the world's leading clay court players in the 1990s, Muster won the 1995 French Open and at his peak was known as "The King of Clay." In addition, he won eight Masters 1000 series titles, placing him joint sixth on the all-time list. Muster is one of only three players to win Masters titles on three different surfaces (clay, carpet, and hard court).

Muster first came to prominence when he reached the final of the French Open junior tournament and the Orange Bowl juniors tournament in 1985. He turned professional later that year and won his first tour title at Hilversum, (Netherlands) in 1986.

In 1988, Muster reached six tour finals, winning four of them. He finished the year ranked in the world's top 20 for the first time.

Early in 1989, Muster became the first Austrian to reach the semifinals of the Australian Open and, shortly after that, the first Austrian to be ranked in the world's top 10. In March, he defeated Yannick Noah in the semifinals of the Lipton International Players Championships in Key Biscayne, Florida (now known as the Sony Ericsson Open) to set up a final match with world no. 1 Ivan Lendl. But in the hours that followed that semifinal victory, Muster was struck by a drunk driver, severing ligaments in his left knee and forcing him to default the final. He flew back to Vienna to undergo surgery. With the aid of a special chair designed to allow him to practice hitting balls while recovering from knee surgery, Muster returned to competitive tennis just six months later.

Carlo Alfredo Piatti (January 8, 1822 – July 18, 1901) was an Italian cellist and renowned teacher.

Piatti was born at via Borgo Canale, in Bergamo and died in Mozzo, 4 miles from Bergamo.

The son of a violinist, Antonio Piatti, he originally began his studies on the violin before switching to the cello. As a cellist, he studied under his grandfather, Gaetario Zanetti, a great cellist. After two years of studying, he joined the theater orchestra, where he played for three months - for ten shillings, half of which his grandfather took. After Zanetti's death, he became a pupil at the conservatorio of Milan under Merighi. He made his concert debut at 15 and started touring at 16. No one doubted the young virtuoso's skill on the instrument, but he did not draw large crowds. As a result, when Piatti fell ill during an engagement, he was forced to sell his cello to cover the medical costs. Franz Liszt invited him to appear as a guest performer at one of his recitals; stunned by what the boy could do on a borrowed cello, Liszt presented him with a superb new instrument. Piatti went on to become one of the most celebrated cellists of his day, as popular for the pieces he wrote as for the robust and unsentimental way he performed them.
