Teo Eng Hock (Chinese: 张永福; 1872 - 5 April 1959) was a rubber tycoon and the founder of the Singaporean branch of the Tongmenghui and later the Kuomintang.
He used the Chinese Reading Room, which was established by fellow revolutionist Tay Sek Tin, to spread his revolutionary ideas.
His bungalow, the Wang Qing Yuan, served as the headquarters of the revolutionists.
In the following year, he founded the pro-revolution newspaper Chong Shing Yit Pao with fellow revolutionists Tan Chor Lam and Lim Nee Soon, and established the Tung Teh Reading Room.
[2] In 1914, the Singapore branch of the Kuomintang began using the Tung Teh Reading Room as a front organisation.
Due to this, Teo was arrested by the Kuomintang after World War II for treason.
