Shortly afterwards, he turned his attention to coaching and from1963-64 guided the top Senegalese football club Foyer France Senegal, now known as ASC Diaraf. He has been the president of the club since 1994 as well as spending a four-year spell in that role during the 1970s.
From 1966-69 Diack was the technical director of Senegal's national football team and the team's successes, which included reaching the Africa Cup of Nations final in 1968, meant important political appointments were quick to follow.
He held the post of Secretary of State for Youth and Sport between 1970-73 and he was also the mayor of his home city and Senegal capital Dakar between 1978-80.
Later, between 1988-93, Diack was the Senior Vice-President of Senegal's National Assembly.
In the continental arena, Diack was President of the African Amateur Athletic Confederation from 1973-2003 and during that period he was also a member of Executive Committee of the Supreme Council for Sport in Africa (SCSA) from 1973-87.
Diack was elected to the IAAF Council at the 30th IAAF Congress in 1976, held in the Canadian city of Montreal, and became Senior Vice-President of the organisation in 1991.
Upon the death of the fourth IAAF President Primo Nebiolo on November 7, 1999, he immediately took over as acting President and Diack was subsequently re-elected unopposed to the position in 2001, 2003, 2007 and 2011 before standing down in 2015.

Born in Turin on July 14, 1923, Nebiolo studied law before a successful business career in construction.
His sporting achievements as a long jumper were relatively modest compared to other IAAF presidents but he quickly gained a reputation as an able administrator, doing much of the work that ensured his native city successfully staged the 1959 World Student Games.
He was elected president of FIDAL, the Italian athletics federation, in 1969 and three years later he was also elected to the IAAF Council before becoming president in 1981.
Nebiolo expanded the IAAF calendar into the form we know it today, especially with the introduction of events such as the IAAF World Junior Championships, as well as moving the show piece IAAF World Championships to a two-yearly cycle.
A pivotal moment in the political history of the IAAF came in 1987 when Nebiolo insisted on changes to the voting structure of Congress, which had been biased towards the 'traditional' powers', to one-member one-vote.
Nebiolo will also be remembered for substantially increasing the sport's finances revenues via commercial sponsorship and developing the IAAF's own television revenues as well as giving much greater attention to the issue of doping in sport and fighting drug cheats.

During World War II, Paulen was a member of the Dutch resistance and was made a Colonel in the US Army. After the end of hostilities, he became the Dutch athletics federation president in 1946 and held that post until 1964. He was the director of the Dutch Olympic Committee between 1965 and 1970 but retained an extensive involvement with athletics, becoming the European Athletics Association president upon its formation in 1970 until 1976, when he was elected as the third IAAF president.
Curiously, at the age of 73, he was two years older than the man he was succeeding but Paulen was active in addressing many of the relevant issues of the changing times. The first IAAF World Cup in 1977 was contested during his brief presidency and he set in motion events that lead to the first IAAF World Championships in 1983.
Paulen stood down as IAAF president in 1981 and died in Eindhoven on 9 May 1985.

In 1931, he was elected as a Conservative Party member of the British Parliament, a position he kept for 12 years, although he was given leave of absence to compete at the 1932 Olympic Games.
He was also head of England's Amateur Athletic Association from 1936 to 1976. After service during World War II as the governor of Bermuda, Burghley was an instrumental part of the organisation of the 1948 Olympic Games in London.
Among Lord Burghley's many significant achievements were assisting the admission of the Soviet Union into international sporting bodies after World War II and dealing with the difficult issue of a divided Germany. Under Burghley - although he was also officially known as the 6th Marquess of Exeter after the death of his father in 1956 - athletics also enhanced its position within the Olympic movement and strengthened its financial position from the distribution of International Olympic Committee television revenues.
However, his final years as IAAF president before standing down in 1976 were turbulent, with many countries outside Europe clamouring for a greater say in the decision making of the Federation. He died on 22 October 1981.

J SIGFRID EDSTROM
He was among the organisers of the 1912 Olympic Games in Stockholm and in this capacity sent written invitations to interested parties to attend the inaugural Congress on 17 July 1912, which lead to the formation of the IAAF.
The hallmark of his 34 years as president was a staunch defence of amateurism but his highly skilful leadership, aided by residing in a neutral country and linguistic skills which included speaking fluent German and English, helped the IAAF steadily expand its scope and influence as well as weather the storms brought about by two World Wars.
Edström stood down as IAAF president in 1946 to become the International Olympic Committee president, a post he held for six years before retiring at the age of 82. He died in Stockholm on 18 March 1964.
