Chess composer
A chess composer is a person who creates endgame studies or chess problems. Chess composers usually specialize in a particular genre, e.g. endgame studies, twomovers, threemovers, moremovers, helpmates, selfmates, fairy problems, or retrograde analysis. Moreover, composers have their own preferred style of composing, allowing their sorting according to composition schools. Some chess composers produce huge numbers of chess compositions, while others try to achieve as much quality as possible and present new works only rarely. It is possible for chess composers to gain official FIDE titles, usually for a given number of problems published in FIDE Albums. For  example, Milan Vukcevich was an International Grandmaster of Chess Composition, as well as an International Master player. The WFCC (World Federation for Chess Composition), formerly known as PCCC, is a branch of FIDE regulating the awarding of titles such as International Grandmaster, International master, Master FIDE and International Judge for chess composition. Schools of composition. Composition school in chess composition is a particular style of creating chess problems, putting emphasis on different aspects of the problem contents and attracting the interest of an important number of chess composers. The best-known composition schools, as they evolved historically, are: Many chess  problems are clearly attributable to a specific one of these schools, but there are many problems that might be attributed to none of these or to more than one of them. Today, many chess composers regularly do work in the area of multiple schools.
