校祖那夏理女士遺訓：行勝於言，言而不行，不若不言。

　　校祖那夏理女士生於1844年3月5日，是美國澳省維路城人。1868年校祖以美國宣教士身份來到中國，她看到社會上重男輕女，女子全無地位。校祖定意把福音帶給中國的女子，培養她們成才。1871年校祖去函美北長老會在費城剛成立的婦女傳道團，建議在中國建立一間女子學校，向婦女及其家人傳道並訓練本地女傳道人，1872年在廣州沙基金利埠創辦真光書院。

　　校祖有強健之體魄、純潔之人格及莊嚴之態度。她慈祥文靜、堅毅勤勞、教導有方、和藹可親、和善幽默、生活儉樸。1923年，校祖在真光服務五十年後，回國頤養，臨別時將其平日儲蓄款項贈予學校。回美後因多年勞瘁過度於1924年1月16日息勞歸主。

　　校祖一生愛主、愛真光，為中國女子教育作出莫大的貢獻。

　　Harriet Newell Noyes, the founder of True Light, would often enlighten young minds with the following saying, "Actions speak louder than words, but when one speaks whilst withholding actions, then surely it would have been better not to speak at all!'

　　Harriet Newell Noyes was born on 5th March, 1844. In 1868, she first arrived in China as a missionary. She soon noticed the existence of sexual inequality within Chinese society. Thus she was determined to pass on the Christian faith to young Chinese women and hoped to cultivate their minds. In 1871, Harriet Newell Noyes wrote to a women's missionary group, which had just been set up by the American Presbyterian Mission North, in Philadelphia. Hoping to evangelize Chinese women and their families, and to provide training for local female missionaries, she proposed the setting up of a girls' school in China. So True Light was established in Canton in 1872.

　　Harriet Newell Noyes was an honourable woman of many virtues. She was strong in body, pure in thought and dignified in attitude. She was quiet , amiable, kind, diligent and humorous. She led a simple life. After serving True Light for 50 years, she returned to the United States in 1923 and donated all her savings to True Light.

　　Harriet Newell Noyes was committed and dedicated to God and True Light. She made an enormous contribution to the education of women in China. Sadly on 16th January, 1924, she passed away in the United States.
