中文摘要：

从学术界广泛引用的牛顿《光学》中的疑问1谈起,随后回顾了马拉、卡文迪什、索德奈尔和爱因斯坦等人在试图量化光所发生的引力偏转方面的贡献,介绍了被世人所遗忘的弗朗提斯克·林克在引力透镜概念起源上极具价值的工作,找出了光线因引力作用而发生弯曲的最早证据,确认了引力透镜概念的出处.弄清了引力透镜概念起源的真相,呈现一个引力透镜概念真实的历史发现过程.

英文摘要：

We begin with the question 1 in the Newton＇s 《optics》 which is widely quoted by academia. Then we review the contributions on quantifying the gravitational deflection of light from the Mara, Cavendish, Soldner, Einstein, and so on. After that, we introduce the valuable work on the concept of gravitational lensing from F. Link. We find out the earliest evidence on the bending of light due to gravity and confirm the conceptual origin of the gravitational lensing. Furthermore, we clarify the truth of the conceptual origin of the gravitational lensing and present a true history of this discovery process.
