S.M Zainul Abidin (1898 - 1969) was a teacher who began his teaching career at the early age of 18 at the Penang Free School. He specialised in teaching Geography and Latin and had taught English, French, Malay and Mathematics. Among his former students were Tunku Abdul Rahman, Tuanku Syed Putra Jamalullail (Raja of Perlis), Tun Dr Lim Chong Eu and Tuan Yusoff Rawa.
Later, he became headmaster of Francis Light School for 10 years and then Inspector of Schools for 5 years. He also taught English through correspondence and had written books for Malay schools.
A founder member of Penang UMNO, he was its president for many years and helped build the UMNO building in Penang. Later he was elected Legislative Councillor for Balik Pulau. Interestingly enough, Zainul Abidin stayed at No 35, Jalan Zainal Abidin (Jalan Yahudi), two doors from the Jewish cemetery, from 1929 until his death in 1969. 
Zainul Abidin is the father of the late Datuk Zainal Alam, who was a senior RTM broadcaster. In 2013, former group chief editor of Star Media Group Berhad Wong Chung Wai, mistakenly attributed Jalan Zainal Abidin to Za’aba in his article. He then urged the Penang government to consider using the correct spelling of Zainul Abidin for the road to prevent future misunderstanding.
Today, the road signs proudly bear the correct spelling to honour the illustrious Penangite, S.M Zainul Abidin.
