CEOs lead a range of organizations, including public and private corporations, non-profit organizations and even some government organizations (e.g., Crown corporations). The CEO of a corporation or company typically reports to the board of directors and is charged with maximizing the value of the entity, which may include maximizing the share price, market share, revenues, or another element. In the non-profit and government sector, CEOs typically aim at achieving outcomes related to the organization's mission, such as reducing poverty, increasing literacy, etc. Titles also often given to the holder of CEO position include president, chief executive (CE) and managing director (MD).  - A president is the leader of a country or a division or part of a country, typically a republic, a democracy, or a dictatorship. The title "president" is sometimes used by extension for leaders of other groups, including corporate entities and social groups.  - Gustave Reese (November 29, 1899  September 7, 1977) was an American musicologist and teacher. Reese is known mainly for his work on medieval and Renaissance music, particularly with his two publications "Music in the Middle Ages" (1940) and "Music in the Renaissance" (1954); these two books remain the standard reference works for these two eras, with complete and precise bibliographical material, allowing for almost every piece of music mentioned to be traced back to a primary source.  - A corporation is a company or group of people authorized to act as a single entity (legally a person) and recognized as such in law. Early incorporated entities were established by charter (i.e. by an "ad hoc" act granted by a monarch or passed by a parliament or legislature). Most jurisdictions now allow the creation of new corporations through registration.  - Cornell University is an American private Ivy League and federal land-grant doctoral university located in Ithaca, New York. Founded in 1865 by Ezra Cornell and Andrew Dickson White, the university was intended to teach and make contributions in all fields of knowledgefrom the classics to the sciences, and from the theoretical to the applied. These ideals, unconventional for the time, are captured in Cornell's motto, a popular 1865 Ezra Cornell quotation: "I would found an institution where any person can find instruction in any study."
