Context: Lee was born at home on 16 September 1923, the first child to Lee Chin Koon, a Semarang born Singaporean, and Chua Jim Neo, at 92 Kampong Java Road in Singapore, then part of the British Empire. Both of Lee's parents were English-educated third-generation Straits Chinese, with his paternal side being of Hakka descent from Dabu County. He was named 'Kuan Yew', meaning 'light and brightness', alternately meaning 'bringing great glory to one's ancestors'. Lee's paternal grandfather Lee Hoon Leong, who was described as "especially westernised", had worked on British ships as a purser, and hence gave Lee the Western name 'Harry'

As prime minister from 1959 to 1990, Lee presided over many of Singapore's advancements. He oversaw Singapore's transformation from an island nation with a high illiteracy rate and no natural resources into a developed country with a high-income economy within a single generation, commonly termed (from his autobiography) as 'From the third world to the first world'. Singapore's gross national product per capita (GNP) rose from $1,240 in 1959 to $18,437 in 1990. The unemployment rate in Singapore dropped from 13.5% in 1959 to 1.7% in 1990. External trade increased from $7.3 billion in 1959 to $205 billion in 1990. In other areas, the life expectancy at birth for Singaporeans rose from 65 years at 1960 to 74 years in 1990. The population of Singapore increased from 1.6 million in 1959 to 3 million in 1990. The number of public flats in Singapore rose from 22,975 in 1959 (then under the Singapore Improvement Trust) to 667,575 in 1990. The Singaporean literacy rate increased from 52% in 1957 to 90% in 1990. Telephone lines per 100 Singaporeans increased from 3 in 1960 to 38 in 1990. Visitor arrivals to Singapore rose from 100,000 in 1960 to 5.3 million in 1990.
