How to describe 陈省身's name
I suggest just explaining the origin:

曾子曰：「吾日三省吾身：為人謀而不忠乎？與朋友交而不信乎？傳不習乎？」——《論語·學而》
The philosopher Zeng said, &quot;I daily examine myself on three points: whether, in transacting business for others, I may have been not faithful; whether, in intercourse with friends, I may have been not sincere; whether I may have not mastered and practiced the instructions of my teacher.&quot;
——&quot;Xue Er&quot; in The Analects (Confucianism). Translated in English by James Legge.

So, you can say something like

陈是耳东陈，省身是「(吾日)三省吾身」的「省身」。

I think Chinese should at least know the idiom 三省吾身(sān xǐng wú shēn), if not, it's an opportunity to teach them :)
PS for pedants: yes, yes, I know 陈 is not composed of 耳 and 东: 耳 should be 阜/. However in common saying, people just say so and everyone can understand!
