Pa Taiwo Akinkunmi died on Tuesday after a brief illness.
One of his children announced his death on Facebook.
He wrote: “Life is indeed transient; I can say boldly that you lived a life with a landmark.
“Continue to rest, my father! Pa Michael Taiwo Akinkunmi (O.F.R.): A great man has gone.”
About the flag
In 1958, while living abroad, Akinkunmi saw an advertisement in a national daily for the submission of designs for the Nigeria’s national flag as the country’s independence from British governance was close.
Among the over 2,000 entries submitted, his was picked.
However, the original design of the flag featured a white band flanked by two green ones with a red sun and streaming rays on the white band.
Although the sun was eventually removed by the committee in charge, Akinkunmi’s design was selected for its ingenuity and profundity.
The green bands represent the forests and abundant natural wealth of the country, while the white band represents peace.
It was hoisted on Independence Day, October 1, 1960, in place of the British Union Jack, while Akinkunmi was awarded 100 pounds when his design was selected.
