Kibaki was born in 1931 in Kikuyu village, Othaya division of Kenya's then Nyeri District, now Nyeri County. He is the youngest son of Kikuyu peasants Kibaki Githinji and Teresia Wanjiku. Though baptised as Emilio Stanley by Italian missionaries in his youth, he has been known as Mwai Kibaki throughout his public life.  Family oral history maintains that his early education was made possible by his much older brother-in-law, Paul Muruthi, who insisted that young Mwai should go to school instead of spending his days grazing his father's sheep and cattle and baby-sitting his little nephews and nieces for his older sister. Kibaki turned out to be an exemplary student. He attended Gatuyaini School for the first two years, where he completed what was then called Sub "A" and sub "B" (the equivalent of standard one and two or first and second grade). He later joined Karima mission school for the three more classes of primary school. He later moved to Mathari School (now Nyeri High School) between 1944 and 1946 for Standard four to six, where, in addition to his academic studies, he learnt carpentry and masonry as students would repair furniture and provide material for maintaining the school's buildings. He also grew his own food as all students in the school were expected to do, and earned extra money during the school holidays by working as a conductor on buses operated by the defunct Othaya African Bus Union. After Karima Primary and Nyeri Boarding primary schools, he proceeded to Mang'u High School where he studied between 1947 and 1950. He passed with a maximum of six points in his "O" level examination by passing six subjects with Grade 1 Distinction.  Influenced by the veterans of the First and Second World Wars in his native village, Kibaki considered becoming a soldier in his final year in Mang'u. However, a ruling by the Chief colonial secretary, Walter Coutts, which barred the recruitment of the Kikuyu, Embu and Meru communities into the army, put paid to his military aspirations. Kibaki instead attended Makerere University in Kampala, Uganda, where he studied Economics, History and Political Science, and graduated best in his class in 1955 with a First Class Honours Degree (BA) in Economics. After his graduation, Kibaki took up an appointment as Assistant Sales Manager Shell Company of East Africa, Uganda Division. During the same year, he earned a scholarship entitling him to postgraduate studies in any British University. He consequently enrolled at the prestigious London School of Economics for a B.Sc. in public finance, graduating with a distinction. He went back to Makerere in 1958 where he taught as an Assistant Lecturer in the economics department until 1961. In 1961, Kibaki married Lucy Muthoni, the daughter of a church minister, who was then a secondary school head teacher.
