Question: What sports governing role has been fulfilled by both Helmut Käser and Stanley Rous?
Context: The regulation of sport is usually done by a sport governing body for each sport, resulting in a core of relatively invariant, agreed rules.  People responsible for leisure activities often seek recognition and respectability as sports by joining sports federations such as the International Olympic Committee, or by forming their own regulatory body.  In this way sports evolve from leisure activity to more formal sports: relatively recent newcomers are BMX cycling, snowboarding, wrestling, etc.  Some of these activities have been popular but uncodified pursuits for different lengths of time.  Indeed, the formal regulation of sport is a relatively modern and increasing development.  This method promotes a sport globally, in a very successful way.  It also promotes the universality of each sport, by ensuring that the same gameplay rules are being practiced worldwide, using a standardized/homogenous international gameplay rule system (sanctioned by the respective international sports governing bodies) that is applied uniformly on all member associations and recognized leagues.  Examples are FIFA in soccer and FIBA in basketball, which have regulated international gameplay rules that are even practiced within US sports leagues today, despite not practicing them historically (which therefore meant that many US sports leagues weren't recognized by international governing bodies in the past, until they began to adopt international rules).  In the sport of basketball the defender/defense cannot call foul. Lawn Tennis Association of Thailand (LTAT) (Thai: ลอนเทนนิสสมาคมแห่งประเทศไทย ) is the national governing body of tennis in Thailand, formed in 1926 it is one of the oldest organised sports governing body in Thailand.  The main aims of the organisation is to develop international level tennis players, improve the infrastructure for tennis and to popularise it in Thailand. Sir Stanley Ford Rous, CBE (25 April 1895 – 18 July 1986) was the 6th President of FIFA, serving from 1961 to 1974.  He also served as secretary of the Football Association from 1934 to 1962 and was an international referee. Jean-Marie Faustin Godefroid "João" de Havelange (] ; 8 May 1916 – 16 August 2016) was a Brazilian lawyer, businessman, and athlete who served as the seventh President of FIFA from 1974 to 1998.  His tenure as President is the second longest in FIFA's history, behind only that of Jules Rimet.  He received the title of Honorary President when leaving office, but resigned in April 2013.  He succeeded Stanley Rous and was succeeded by Sepp Blatter.  João Havelange served as a member of the International Olympic Committee (IOC) from 1963 to 2011.  He was the longest-serving active member upon his resignation.  In July 2012 a Swiss prosecutor's report revealed that, during his tenure on FIFA's Executive Committee, he and his son-in-law Ricardo Teixeira took more than $41 million in bribes in connection with the award of World Cup marketing rights. The role of an England national football team manager was first established in May 1947 with the appointment of Walter Winterbottom.  Before this, the England team was selected by the "International Selection Committee", a process in which the Football Association (FA) would select coaches and trainers from the league to prepare the side for single games, but where all decisions ultimately remained under the control of the committee.  A 1–0 defeat by Switzerland prompted FA secretary Stanley Rous to raise Winterbottom from "National Director of coaching" to "Manager". The American Bicycle Association (ABA) is a US-based BMX sports governing body in Gilbert, Arizona created by Merl Mennenga and Gene Roden in 1977.  It is the largest sanctioning body in the United States concerning BMX.  It has tracks in Canada and Mexico as well as in the USA.  It was and is known for its efficiency in running events known as Nationals, where BMX racers from around the country race in competition for points and in the case of Professionals, money, to determine who will earn the right to run a National No. "1" plate in the several divisions the following year.  The other leading sanctioning body, the National Bicycle League (NBL) also holds Nationals as do several smaller regional governing bodies. The 1934 FA Cup Final was won by Manchester City in a 2–1 win over Portsmouth.  The match is most remembered for a young Frank Swift's heroics in goal and the predictions of City forward Fred Tilson.  The match was also refereed by future FIFA president Stanley Rous, in his penultimate game as an official. The Inter-Cities Fairs Cup, sometimes referred to as the European Fairs Cup, Fairs Cities' Cup, or simply as the Fairs Cup, was a European football competition played between 1955 and 1971.  The competition was the idea of Swiss pools supremo Ernst Thommen, Ottorino Barassi from Italy, and the English Football Association general secretary Stanley Rous, all of whom later became senior officials at the world governing body, FIFA.  As the name suggests, the competition was set up to promote international trade fairs. Friendly games were regularly held between teams from cities holding trade fairs and it was from these games that the competition evolved.  The competition was initially only open to teams from cities that hosted trade fairs and where these teams finished in their national league had no relevance.  Early competitions also featured a "one city, one team" rule.  After 1968, it was sometimes referred to as the Runners-up Cup, with teams now qualifying based on league position.  In 1971, it came under the auspices of UEFA and was replaced by the UEFA Cup. A sports governing body is a sports organisation that has a regulatory or sanctioning function.  Sports governing bodies come in various forms, and have a variety of regulatory functions.  Examples of this can include disciplinary action for rule infractions and deciding on rule changes in the sport that they govern.  Governing bodies have different scopes.  They may cover a range of sport at an International level, such as the International Olympic Committee and the International Paralympic Committee, or only a single sport at a national level, such as the Rugby Football League.  National bodies may or may not be affiliated to international bodies for the same sport.  The first international federations were formed at the end of the 19th century. Helmut Käser (14 November 1912 – 11 May 1994) served as the General Secretary of international governing body of association football FIFA, from April 1960 to June 1981.  Käser served as general secretary under three presidents of FIFA, the Englishmen Arthur Drewry (1955–1961) and Stanley Rous (1961–1974) and from 1974 until 1980 under the Brazilian João Havelange.
