Former First Lady Lucy Kibaki's sudden death has shocked many Kenyans across the country. Her demise comes so soon after her recent admission at Nairobi Hospital, although it's said she had been unwell for about a month.

She passed away early Tuesday morning while undergoing treatment in the UK at the Bupa Cromwell Hospital in London.

As we celebrate the life she lived, how about we take a look at a few things you may not have known about former President Mwai Kibaki's late wife.

1. She is a trained teacher

After completing high school, Lucy Kibaki trained as a teacher and succeeded in her career attaining the position of principal in a teachers training college in Kiambu.

2. She is not on any social media platform

There has been no trace of the former First Lady's name on social media and is known to be very private individual. She never expressed her opinion on social media and the only way to get her view on anything, was listening to her public speeches.

3. She missed the last political events of her husband's career

Lucy Kibaki failed to attend several political events leading to the end of President Mwai Kibaki's tenure in office, including the handing over ceremony in 2013. This was allegedly attributed to the fact that she was not ready to leave State House, which had been her home for years.

4. She is a patron of the Kenya Girl Guides Association

Though many are not aware of this, Lucy Kibaki was a very revered person in the Kenya Girl Guides Association and is one of the few leaders who has ensured that the association's functions run smoothly.

5. She participated in a lot of charity events

Despite being a no-nonsense woman, the former First Lady always participated in charitable work including supporting the less fortunate in the community.

6. She was involved in AIDS Awareness Projects

Lucy Kibaki was one of Kenyan women leaders on the forefront in th fight against HIV/AIDS in Africa, which was why she was elected as the Chairperson of the 40 African First Ladies against AIDS, during Mwai Kibaki's tenure.

7. She was a controversial woman

Okay, maybe this may not be new to most of us, but Lucy Kibaki was one of the most staunch and strict first ladies in East Africa.

She launched verbal and at times physical attacks at various journalists and diplomats if any negative thing was said or publicized about her. She would get offended easily if she felt that an individual, group, or media house did not give her the respect she deserved as a First Lady of Kenya.
