????美國總統奧巴馬周三提名詹尼特?耶倫接替本?伯南克，出任下屆美聯儲（Federal Reserve）主席。現在，很多美國人都已經知道，耶倫作為美聯儲首位女性主席以及近30年來執掌美國央行的首位民主黨人將被載入史冊。

????但有些事情你可能未必知道。

????耶倫57歲時還跑了一次半程馬拉松。

????周三，美國總統奧巴馬在提名耶倫擔任下屆美聯儲主席時說：“她是一位杰出的領導者，她很強悍，原因不只是因為她來自紐約布魯克林。”

????奧巴馬或許還應該加上一句，今年67歲的耶倫很強悍，幾年前還跑完了一次半程馬拉松。她57歲的時候才迷上跑步，當時她是加州大學伯克利分校（University of California-Berkley）的教授。13英里多的路程她花了約3小時。

????這需要體力。

????耶倫的集郵非常精美。

????這位經濟學愛好者也是一個集郵迷。

????據美聯儲在8月份發布的年度財務披露文件顯示，耶倫是美聯儲理事當中最富有的人之一，她的投資在2012年價值至少480萬美元。

????在她的投資（大部分與其丈夫共同持有）中，包括價值15,000至50,000美元的郵票。顯然，她們家持有這項收藏已經多年；耶倫從她母親那里繼承了差不多數額的郵票收藏。

????耶倫角逐美聯儲主席的主要對手是她的學生。

????是的，說的就是拉里?薩默斯。

????1976年，耶倫在哈佛大學（Harvard University）擔任講師教授宏觀經濟學時，薩默斯是班上的一名學生。

????多年之后，薩默斯擔任哈佛大學校長，還成了美聯儲主席的熱門人選，結果他主動退出了角逐，看著曾經教過他的教授獲得了提名。

????哈佛這個圈子可真小。

????耶倫太愛經濟學了，她嫁給了經濟學大師。

????耶倫出類拔萃，她丈夫在自己的領域同樣成績斐然。他就是獲得諾貝爾獎獲得者、經濟學家喬治?阿克洛夫。兩人于1977年相遇，當時他們都是美聯儲的經濟學家。

????阿克洛夫憑借非對稱信息研究與另外兩位美國經濟學家共同奪得了2001年諾貝爾獎，他也寫過很多有關金融危機和銀行監管的著作。

????President Obama on Wednesday tapped Janet Yellen to succeed Ben Bernanke as the next chairman of the Federal Reserve. By now, many Americans know Yellen could go down in history as the first woman to lead the Fed, as well as the first Democrat to head the central bank in almost 30 years.

????Here are a few facets you might not know about.

????At 57, Yellen ran a half marathon.

????As President Obama said Wednesday when he nominated Yellen to be the next Fed chair, "She is a proven leader and she's tough, not just because she's from Brooklyn."

????Obama should have added that Yellen, currently 67, is tough for having finished a half-marathon a few years ago. At 57, she took up running while a professor at the University of California-Berkley. The 13-plus mile run took her about three hours.

????Now that takes strength.

????Yellen has a fancy stamp collection.

????The lover of economics is also a lover of stamps.

????Yellen is one of the wealthiest members of the Federal Reserve board of governors, with investments worth at least $4.8 million in 2012, according to annual financial disclosures the Fed released in August.

????Included in her investments, mostly held jointly with her husband, is a stamp collection worth between $15,000 and $50,000. Apparently it has been in the family for years; Yellen inherited a stamp collection with that same range from her mother.

????Yellen's main rival for Fed Chair was also one of her students.

????Yup, that's Larry Summers.

????In 1976, Yellen was a lecturer at Harvard University teaching a macroeconomics class whereSummers was a student.

????Years later Summers would run Harvard University and become the frontrunner for Fed chair,only to withdraw himself from the contest and watch his former professor take the nomination.

????Harvard, it's a small world.

????Yellen loves economics so much she married economic greatness.

????Yellen is impressive, and so is her husband in his own right. He is Nobel Prize-winning economist George Akerlof, whom she met in 1977 when they were both economists at the Fed board.

????Akerlof shared the 2001 prize for his work on asymmetric information and has written about the financial crisis and banking regulation.
