Born on December 20, 1953, in Sagamu, located in Ogun State, Nigeria, Adebayo Ogunlesi was raised in a highly academic family. His father, Professor Theophilus Oladipo Ogunlesi, holds the distinction of being the first Nigerian professor of medicine.
Ogunlesi’s early education took place at King’s College Lagos, one of Nigeria’s most prestigious secondary institutions. Excelling in academics, he earned a Rhodes Scholarship to attend Oxford University, where he graduated with first-class honors in Philosophy, Politics, and Economics.
Following his undergraduate degree, Ogunlesi went on to complete a JD–MBA at Harvard Law School and Harvard Business School, where he contributed to the Harvard Law Review. His dual degrees in law and business positioned him uniquely for leadership roles in both sectors.
Legal and Financial Career Path
Ogunlesi’s professional journey began with a rare opportunity as a law clerk to U.S. Supreme Court Justice Thurgood Marshall, a role that gave him significant exposure to legal thought at the highest level. Afterwards, he joined Cravath, Swaine & Moore, a well-known law firm based in New York.
In the early 1980s, he shifted into investment banking, joining First Boston, which later became Credit Suisse First Boston (CSFB). His rise within the company was rapid. He eventually became Executive Vice Chairman, Chief Client Officer, and Global Head of Investment Banking.

GIP’s Merger with BlackRock
One of the most notable developments in recent years was the $12.5 billion acquisition of GIP by BlackRock in 2024. The deal combined stock worth approximately $9.5 billion and $3 billion in cash. It created one of the largest multi-asset infrastructure investment platforms globally, with over $150 billion under management.
The agreement cemented GIP’s legacy as the world’s largest independent infrastructure manager and amplified Ogunlesi’s global standing in the finance world.
