出生于台湾的孫賢鉥先生，早年在美国获得博士学位，后长期在澳大利亚地质调查所工作，他在网上发现〈五柳村〉后即成为忠实读者和热情的支持者。先后来信数十封，对如何办好〈五柳村〉提供了许多有价值的意见和大量参考资料，推荐文章和作者。
先生热爱中华文化，与陶永强君就英译中国古诗词，作了仔细的推敲，成为好友。
由于与孙先生联系的信箱中断三月有余，此次过温哥华始从陶永强君处得悉，先生于2004年11月19日即因病在澳大利亚之堪培拉住院，至2005年2月23日确定为胃癌，旋即于当地时间2月25日6时15分去世。享年61岁。学术界痛失一位世界级的地球化学家！五柳村痛失一位良友！

台湾大学网站设有沉痛悼念 孫賢鉥先生In memory of Dr. Shen-su Sun  专页
http://memory.gl.ntu.edu.tw/ 有许多悼念文章。这里转发的是中国科学院广州地球化学研究所孙卫东所写：

In memory of Dr Shen-su Sun, my dear mentor A world-class scientist and tireless fighter, Dr Shen-su Sun has left us with regret, after battling against cancer for about 10 year with superb wisdom and iron determination. I was told Dr Sun had suffered a great deal when he passed away. He was in such great pain that he bit his tongue and his fingers. I know he did so because he did not want to leave us. He was concerned about so many things and so many people in this world.
很多地学界的朋友都知道，先生帮助、指点过很多人，特别是中国的年轻人。记得最后一次通电话，先生不顾护士的多次提醒，在病床上跟我讲了半个多小时。他反复提到大陆的几位年轻同行正在做的工作，还不无遗憾地笑者说：“我可能是帮不上忙了”。当时我想：就是雷锋也不过如此吧。更让我唏嘘不止的是，没想到这竟成了我最后一次聆听先生的教诲：由于药物的副作用，先生很快双耳失聪。

Many geologists know that he had helped and instructed many people, especially young scholars from China. I remember the last time I called him. He talked to me over the phone for about half hour, ignoring the warnings from the nurse. He kept mentioning the work of several young researchers in the mainland, saying with smile, but not without regret: “I probably won’t be able to help them.” At that time, I thought: “Well, even Lei Feng, the role model for so many, would only be able to do as much as this.” I didn’t realize that was the last time I was able to hear his advice. Due to the side effects of medications, he lost his hearings soon after that.
在众多地学界的同行中，我可能是近年来受先生惠泽最多的人之一。1999年至2003年间，我在澳大利亚国立大学读书时，有幸追随先生左右，时时聆听教诲。西澳的李正祥博士曾对我说：别人能聆听孙先生只言片语，已经是终生受益，你小子可要珍惜！
Of the numerous researchers in geoscience, I am probably the one who has benefited most from his help. From 1999 to 2003, I was privileged to be able to work under his supervision, and to listen to his instructions, during my PhD studies at the Australian National University. Dr Zhengxiang Li of the University of WA said to me: Other people only had bits and pieces of Dr Sun’s advice and benefited for their lifetime. You must cherish your opportunity! 我与先生的交往始于1997年。当时先生顺访科大，我被选为研究生代表向先生汇报研究工作，之后便开始了与先生的书信交流。记得我的第一封电子邮件是用中文写的。先生回信说：你中文不错……我们以后最好用英文交流，这样你可以练习英文写作。之后的一年多的时间里，我与先生有近千封电子邮件往来，合在一起有四、五百页之多（注一）！在这期间，先生从学问到做人，从地球化学到英语写作，给了我全面的指导，使我得以在短时间内了解到地球化学的许多前沿领域和作学问的一些要诀。后来我得知，很多年轻人曾象我一样幸运地得到了先生的指点。
I started communication with Dr Sun in 1997, when he was visiting University of Science and Technology of China. I was selected as postgraduate representative to report to him our work and studies. After that we began our email communications. I remember my first email was written in Chinese. He replied, saying “Your Chinese is not bad… but we’d better communicate in English from now on so that you can practice your English writing. For more than a year after that, I had nearly a thousand email correspondences with him, totaling about four to five hundred pages altogether. During this period, he gave me comprehensive guidance, both academically and morally, from geochemistry to English composition, which enabled me to be aware of many recent advances in the field of geochemistry and know some useful ways to study. I later knew that many young scholars were like me in having the fortune of receiving advice from him.
2000年初，先生被确诊为胃癌晚期。在这之前，先生的胃已经痛了五年，可惜被医生误诊为肌肉疼。据当时负责为先生做胃部切除手术的医生回忆说，2000年手术时先生的病情很糟，已经有癌细胞扩散的迹象，他没有想到先生可以撑到现在。五年来，先生就是在这种病痛的折磨中为众多象我一样的年轻人指点迷津！
Dr Sun was diagnostic with postage stomach cancer early 2000. He had been complaining about stomachache for five years before that. Unfortunately, until then he was diagnostic with muscle pain. According to the memory of the surgeon who did the operation to remove the cancer from Dr Sun’s stomach, his conditions were pretty bad at that the time of the operation, with signs of cancer cell diffusion. It was really a miracle that he was able to survive until now. For five years, he was tirelessly guiding many young scholars like me as he was suffering from the disease!
2000年12月我做博士论文“中期报告”（注二）。考虑到先生正在做化疗，我故意在答辩的前一天晚上才将 “中期研究报告书”转交给他。原指望他可以不用费心批改，不料第二天早上我在门前的台阶上见到了我的报告书。原来，先生连夜将80多页的报告书作了认真的批改，到凌晨才改完，然后开车送到我家门口！
I was scheduled to do my midterm report for my PhD thesis in December 2000. Considering that he was doing chemotherapy at that time, I purposefully didn’t pass on my progress report to him until the evening before the seminar, thinking that he did not need to spend time reading and commenting on it because there would not be enough time. To my great surprise, I saw my report on the step in front of my door the following morning. It turned out that he spent the whole night carefully reading through and making detailed comments on the report. He didn’t finish it until early morning before he drove all the way to deliver it to my house!
孙贤鉥先生是一位伟大的民族主义者。在与他的交往中，我真真切切地感受到了他是多么热切地希望中华民族科技腾飞，民富国强。在我看来，对中华民族的至诚热爱是先生高尚情操的原动力之一。正是对中华民族的爱，促使先生夜以继日地工作。很多时候他手上都有近十篇年轻人的文章等着他修改。他常对我说：没什么大不了的，少睡点觉而已。即使在病重期间，先生仍念念不忘帮助大陆和台湾的同行们修改文章。
Dr Sun was a great compatriot. From my personal observation, I can see he was deeply passionate about raising the standard of science and technology and the prosperity of China. His profound love towards the Chinese people is a driving force of his moral integrity. It became his routine to work round the clock. Most of the time he had scores of papers to read and comment on, papers written by young scholars. He often said to me, “It’s not a big deal for me to sleep a bit less.” Even when he was seriously ill, he was still thinking about reading papers for colleagues in the mainland and in Taiwan.
也正因如此，2002年，在化疗后没有多久，身体尚在恢复之时，先生便应邀到北京大学讲学三个月。昨天北大的艾先生来信说：
In 2002, shortly after he finished chemotherapy, he accepted an invitation to lecture at Peking University for three months, when he was still recovering. Professor Ai of Peking University wrote to me yesterday: “
……孙先生生活极尽简朴。有一次他去校内理发店理发，只肯花三元钱让人用推子剃头发却不肯再花三元钱冲洗，满头的碎发回到住处自己洗。然而先生却把北大给他的讲课费壹万圆（后来又将在中国地质科学院离子探针中心作学术指导时所得补助壹万伍千圆）交给我，在大别山深处河南省商城县伏山乡有12个家庭破碎（或父母残障）的孩子先后38人次获得学费资助，得以继续小学和初中教育（在将来的若干年里，名单会越来越长）。目前他们只是知道有一位科学家爷爷支持他们念书，他们将来若能走出深山，能自立于世，将永远感念先生之德。 我想哭送我的孙老师，并代表那些深山里的孩子们哭送他们的科学家爷爷，愿先生一路走好…”。 “…Dr Sun lives a very simple life. Once he went to the campus barber shop to have a haircut. He just spent three yuan having his hair cut. He could have spent another three yuan having his hair washed, but he didn’t. Instead, he came back to his room to wash by himself. Yet he donated all his lecturing income of ten thousand yuan to assist 38 children from financially-disadvantaged families in the Dabie Mountain to go to school. (He later on donated another fifteen thousand yuan from his earning at the SHRIMP Centre.) At present, the children only know that they are supported by a scientist grandpa. May Dr Sun rest in peace…”
先生的名讳中有个“鉥”字。其含义：一是长针，二是引导。先生人如其名。很多人都知道他是一名犀利的批评家，针矾时弊、毫不留情。他更是一位出色的导师，对学生、晚辈循循善诱，宽严并济。正因如此，先生有很多敌人，但同时他有更多的朋友。
Dr Sun’s name, ‘su’, written in Chinese character with a metal radical and a meaning component ‘art, technique, method’, has two meanings: 1. long needle; 2. guidance. This character characterizes Dr Sun as a man. He is well-known as a sharp critic, who is relentless in criticizing wrong ideas. At the same time he is an outstanding teacher, earnestly and tirelessly guiding young students and researchers in their studies and research. He was very strict with them and at the same time quite tolerant. For this reason, he may have many ‘enemies’, but he has more friends. 很多与先生有过交往的朋友都深深地被先生的率直和真诚所折服。有人曾对我说：（与先生交往）要先经得起骂—世界上很少有第二个人会如此坦诚地指出朋友的缺点—他是一位难得的诤友！先生的两篇杂文：《对中国大陆地球科学研究和发展的一些批评和建议》（附件一）和《對台灣地球科學界的一些批評和建議》（附件二），在某种意义上可以说正是他风骨和气节的体现。现在，重新拜读两篇杂文，更加让人百感交集。
Many friends are impressed by Dr Sun’s frank and straightforward personality, and his sincerity. Some said to me: (if you want to get along well with Dr Sun) you must first of all be able to stand blunt criticisms. There is hardly anyone else in the world like him who would point out his friend’s shortcomings in such a frank and sincere manner. He is a true friend who is hard to come by! Two of his essays, ‘Some Criticisms and Suggestions on the Research and Development in Geoscience in China’ (attachment 1), and ‘Some Criticisms and Suggestions on Geoscience in Taiwan (attachment 2) are embodiments of his personal integrity. Today, as we re-read these two articles, we are even more deeply moved.
都说“人生得一知己足矣”。又说“知己易得，诤友难求”。中国地学界是否应该为曾经拥有孙贤鉥这样一位真诚无私的诤友而庆幸呢？ They say ‘one is lucky to have a bosom friend in life’. They also say ‘it’s easy to find a friend, but hard to come across a true one.’ Aren’t we lucky to have Dr Sun as a true and selfless friend?
记得刚到澳大利亚时，我十分亢奋，思路异常的活跃。几个星期内连续向先生兜售了我私下琢磨了很久的有关板块运动、地幔柱、核-幔相互作用等的“孙氏理论”，着实把他吓了一跳。先生发现我才是最需要批评的人，一千封电子邮件竟没有让我脱胎换骨。为此他给我发了一封很长的电子邮件，并让我重新阅读他的杂文（附件一、二）。随后又亲手抄写一份周剑云的《徐君悲鸿留法序》（附件三），并加了两条批注（注三），送给我：
I remember when I first arrived in Australia, I was extremely excited, and my mind was overactive. For several weeks, I kept selling my ‘theory’ to Dr Sun about ….. and about the interaction of nuclear and …, which indeed took him by surprise. He realized that I definitely needed to be criticized. His thousand emails failed to rid me of my wishful thinking. For this reason, he wrote me a long email, suggesting that I reread his essays (see attachments 1 and 2). Later on he hand copied a note by Zhou Jianyun (attachment 3) ‘On Seeing Mr Xu Beihong off to Go to France to Study’, adding two footnotes (Note 3) and sent to me: “（1）困境之根：许多年青人因缺乏资讯，图书馆没有新的国际杂志，他们没有适当的人指导，只好凭感觉，靠才气，自己发展。他们以想象的东西取代踏实的知识，以玩票的资格去参加国际大赛。然而，在缺乏许多基本知识的情况下想“庖丁解牛”何谈容易？！该如何使他们“识迷途而知返”？（2）可造之才并不等于已成才。徐悲鸿以画马出名, 但他留学前所画的马实在是“见不得人”的马。他到了法国之后踏实地从基本功开始学习。“洗心革面”有何困难？”（注四） 。
“(1) The root of dilemma: For lack of information and lack of adequate supervision, many young people had to make their own way with some intellectual talent and wishful thinking. They take imagination for solid knowledge. They go to international tournaments as if they were playing a game. Yet how could one have a thorough understanding of something without having the basic knowledge? How to make these people aware that they are going in the wrong direction and should turn back? (2) A talented person is not necessarily a talent. Xu Beihong is famous for his paintings of horses. Yet before he went overseas to study, his horse was indeed anything but a horse. After he arrived in France, he started from the very beginning, gradually and steadily laying down a good foundation. Is it really that hard to reform oneself?” (Note 4)
先生的批注对我来说，确实是犹如当头棒喝，使我从此“洗心革面”。 His criticism was a stern warning to me. From then on I started to reform myself. 先生一生道德文章享誉中外（注五）。他经常提到的一个词就是real professional （真正的职业选手）。我曾经问过先生职业选手与业余选手的本质差别在哪, 先生说: 业余选手总是欣喜自己的每一点进展,而职业选手总是不断地发现自己的不足, 不断地完善自己。 Dr Sun’s has enjoyed a fine reputation at home and abroad. (Note 5). One thing he often mentioned was ‘real professional’. I asked him the difference between a professional player and an amateur. He said, “An amateur is always delighted at every bit of progress he makes, but a real professional is always finding his own weakness, and constantly trying to improve.’ 追求完美、追求真理，这正是先生一生的写照。 Throughout his life, Dr Sun was always in relentless pursuit of perfection and truth.
都说男儿有泪不轻弹，可每每想起先生的音容笑貌，我总是不知不觉泪眼朦胧。我想对先生说的是：先生您放心地去吧。我们会把您的精神传承下去！发扬光大！
A Chinese saying goes, ‘A man will not shed his tears easily.’ However, each time I think of Dr Sun, my eyes are filled with tears. A just want to say to Dr Sun: Rest in peace, Sir. I promise we will carry on your legacy.’
注一：每次通信，先生总是认真修改我的英语。
1. Dr Sun always corrected my English each time he wrote to me.
注二：中期报告（MIDTERM REPORT）相当于澳大利亚攻读博士学位的“资格认证”。一般在开始读博士一年半至两年时进行。
2. A mid-term report is a confirmation of PhD candidature in Australia, which is generally to be submitted 18 months after enrolment in a PhD program.
注三：我是1999年8月1日到达澳大利亚的。先生于1999年9月17日赠《徐君悲鸿留法序》。2002年底我将周剑云的《徐悲鸿君留法序》及先生的批注输入计算机，先生随后将其发到“五柳村”网站。
3. I arrived in Australia on 1 August, 1999. Dr Sun presented the Note to me on 17 September. I processed the Note and Dr Sun’s comments onto the computer at the end of 2002. Dr Sun then posted it to the website Wuliucun. I
注四：我太太曾问先生这两条批注是否在说我。先生说不全是，但我是个典型的例子。
4. My wife asked Dr Sun if he was using the two comments to criticise me. He said: No, not entirely. But I was a typical example.
注五：我个人根据Web of Science的数据不完全统计，到2005年先生的SCI引证次数约一万次左右。其中，Sun&McDonough, 1989，被引用约2800次，另有多篇有关铅同位素和元素地球化学的文章被引用次数在500至800次之间。值得指出的是先生帮助别人修改论文，通常拒绝署名。
5. According to my incomplete count from Web of Science, by early 2005 Dr Sun was cited about 10,000 times in SCI. Of these, Sun & McDonough 1989 was cited 2800 times, plus several other papers on lead isotope and trace element geochemistry which were cited between 500 to 800 times. It is worth pointing out that Dr Sun often refused to sign as coauthor even though he put a huge amount of time and effort working with others. Weidong Sun
