Heng Ee High School was founded by a Belgian Roman Catholic expatriate missionary priest, Dato' Father Arthur A. Julien, from the Paris Foreign Missions Society in 1957.

He conducted missionary work with the community in Batu Maung, Bayan Lepas and Sungai Dua, and also regularly visited the detainees in Pulau Jerejak.

[citation needed] His ability to converse in Mandarin and later Hokkien, endeared him to the local Chinese community.

Heng Ee High School celebrated its Golden Jubilee on 9 September with much pomp and ceremony.

A milestone was set when three Form 4 students received three Gold Awards with their invention of FloodWarn, a flood-warning detector.

The Chinese Cultural Dance Troupe secured two Gold Awards in the 2010 China-Asean Youth Dance Interaction and Competition and the Harmonica Band won three Gold Medals and four Silver Medals in the Asia Pacific Harmonica Competition.

Heng Ee High School was presented the Champion Award for the Co-curricular Category (Clubs and Societies) by the MOE on 11 November 2010.

In 1999, the school topped up another floor on Block E which includes an additional 7 classrooms and another air-conditioned Music Room II to accommodate the increasing number of students.

Bangunan Wawasan is also equipped with the necessary infrastructure and ICT facilities to provide the students with a positive and supportive environment that is conducive for academic and social growth.

Penang Chinese Chamber of Commerce had donated RM2 mil for the construction of Bangunan Wawasan along with other efforts and sponsors.

This prompted the school board of directors to rename the building as Bangunan Wawasan Penang Chinese Chamber of Commerce.

As the number of students increased gradually over the years, the school decided to make it permanent instead of shifting back to its original site.
