In 1902, the school was founded by Father A. Hopfgartner, who was born on 5 January 1874, and later suffered a stroke and died on 15 May 1949. A clock tower and bronze plaque were erected in his memory on the school premises. By 1905, the school was moved a two storied building at Lanang Road. The lower floor was used as classrooms, with the upper floor used as hostels. The school was then transferred to Mission Road in 1907. The following year Father Hopfgarther was replaced by Father Vincent Halder, the longest serving principal of the school. In 1928, Standard Four (now Primary Six) was introduced followed by the introduction of Standard Five (now Form One) in the succeeding year. The school has classes up to Standard Seven (now Form Three) and the number of pupils had reached 300. In Father Halder's final year as Principal, the Chinese language was added to the school curriculum and the Chinese department was established. After his death, Father Halder was succeeded by Rev. John Vos, who was succeeded by Rev. James Buis in 1938.

From 1941 to 1946, the school was put to a half due to the Japanese Occupation during the World War II. Half of the School was destroyed in the bomb raid of the Australian Forces.

The de La Salle Brothers took control of the school by 1954, with Bro. Fridolin became the principal. The First Cambridge School Certificate was held (now Form Five). English was taught in the morning and Chinese was taught in the afternoon. The school became an aided school in 1956. SRB Sacred Heart, a primary school, was founded and Bro.
