On Wednesday, Kale was reported to have died in London, United Kingdom (UK), following an unexplained illness.
The president of the Alumni Association of the National Institute (AANI), Ambassador Emmanuel Obi Okafor, made the announcement of her passing in a statement on Thursday.
In the statement, Okafor called Kale's passing a "irreparable loss," and the president of AANI said her family will make burial plans public.
He declared, "AANI and the country as a whole will never forget the amazing legacy of the legendary Major General Aderonke Kale (rtd) mni, who had been a trailblazer in Nigeria's medical and military history."
The statement, which was signed by S. K. Usman, the former army spokesperson, said, "May her gentle soul continue to rest in peace, Amen."
The first female major-general in the Nigerian Army was Kale, a psychiatrist in the army. She became the Nigerian Army Medical Corps' commanding officer.
She completed her medical training at University College, which subsequently changed its name to University of Ibadan. After that, Kale attended the University of London to specialize in psychiatry.
Thomas Adeoye Lambo, the first psychiatrist in Africa, served as Kale's inspiration to become a psychiatrist.
She married Oladele Kale, a professor of social and preventive medicine, and the two of them had five boys together.
