Hong Chaosheng, an academician of the Chinese Academy of Sciences, was one of the pioneers in China's semiconductor physics research and cryogenic undertakings, as well as a distinguished experimental physicist in the international academic community. Based on detailed historical materials and specific case analyses, this paper explores the profound influence of his family scholarly background and academic mentorship on moral character, professional competence, academic attainment and academic vision. It presents Hong Chaosheng's important academic achievements in the fields including low–temperature impurity conduction in germanium single crystals, and demonstrates his personal charm of being sincere, plain and indifferent to fame, alongside his spirit as a scientist embodied in rigorous scholarship, patriotism and dedication.
