[The Conversation Africa] Few witnessed the building of the young Kenyan state from within as did Ngina Kenyatta, the widow of Kenya's first president, Jomo Kenyatta. Mama Ngina, as she is known, will mark her 90th birthday on 24 June 2023. She was by her husband's side when Kenya won independence 60 years ago and for many turbulent years thereafter. Although Kenyatta was polygamous, it was the younger Mama Ngina who took on the roles of first lady.
