Jean-Claude Ngumire was born in Kigali, the capital of Rwanda. In 1985, he was admitted to Nyundo art academy, the only educational institution in Rwanda that could issue official diplomas. He made his debut as a graphic illustrator seven years later. Since then, he has made drawings for various newspapers and magazines. He has illustrated school books and written children's books. In 1998, Ngumire contributed to 'Au sécours! L'Afrique en danger', a collection of stories about environmental protection, published at the initiative of Calao, a magazine for young people.
He drew a series of comics for Huguka magazine, based on the scenario of Charles Rukundo. These comics were collected and published under the title of 'Umwana nk'undi'. Along with friends, Ngumire started the magazine Bakame. Only three issues were published, and then war broke out. He keeps a book with sketches of his war memories at home. Jean-Claude has been living in the Netherlands (Ommen) since 2002. He is now a digital sketch artist and works for companies such as The Rep's, an agency for creative professionals in Amsterdam.
