Born in 4th October in Curitiba, Brazil in 1947, Igor Cornelsen joined the Federal University of Parana, in 1975 where he studied engineering. At that time, the institution was the only one in Parana state offering that course, and as such, it had very competitive admission requirements. However, Igor was admitted and studied engineering for two years before he made up his mind to study economics in the same institution.

He graduated in 1970 and got the first job with an investment bank. By then, investment bank jobs were favorite for engineers, due to the valuable skill of calculating compound interest rates using sliding rules bearing in mind, calculator and computers were not common.

With time, Igor Cornelsen became very successful in the bank job, and eventually proceeded to Rio where he was offered a better job to work as an Investment Banker. He excelled in his position and got promoted to the Multibanco Board of Directors in 1974, and after two years, he was promoted as the CEO of Bank of America where he was working.

After acquiring Multibanco by the Bank of America in 1978, Igor Cornelsen had to move on to pursue greener pasture elsewhere. Later, he got an appointment with Unibanco, which was a very successive leading company in Brazil. Igor worked with Unibanco until 1985, the time when inflation was exploding, and the situation could not contain him. Afterward, he moved to Libra bank PLC, which is a merchant bank from London.

Moving to Libra bank was a turning point to Cornelsen career. He was first paid his salary in US dollars, and the gesture opened Cornelsen to the new whole world of investment. His stint was successful at Libra, before moving to Standard Chartered Merchant Bank with his London workmates to become a member of the Board of Directors and representative in Brazil. He worked as a board member for seven years until 1995 when he moved on to start his investment firm where he now works as the investment manager.
