这个概念很早就有了。 约翰·D·洛克菲勒于1882年成立了他的家族办公室。本世纪Family Office的数量暴涨。 大概有5000-10000个在美国和欧洲， 还有亚洲（新加坡和香港）。
虽然Family Office的首要目的是管理金融资产，但是那些有着几百号“高级管家”的大型家族办公室， 员工需要处理大小适宜， 工作范围从税务和法律，需要上能预订喷气式飞机，下能逗宠物开心。

Family office一百多年前就已经有了。
Family office, 简单来说，一些很富有的家族会成立family office, 找人专门管理旗下财产的运作。 比如香港明星李嘉欣嫁的许家。创始人续爱周为了不让子孙后代把自己的财富败光， 他参照国外的办法，成立了家族基金。

Paragraph 4
The costs of bringing such expertise in-mansion means that they generally make sense only for those worth over$100m, the top 0.001% of the global pile. Asian tycoons such as Jack Ma ofAlibaba have created their own fiefs. The largest Western family offices, suchas the one set up by George Soros, an investor and philanthropist, oversee tens of billions and are as muscular as Wall Street firms, competing with banks and private-equity groups to buy whole companies.
只有顶级富豪（资产超1亿美元，占全球0.001%）才能养得起这种顶级专家。亚洲大亨，如阿里巴巴的马云就有自己的家族办公室。 西方最大的家族办公室，比如投资者和慈善家的乔治索罗斯所设立的办公室，它监管着数百亿美元，与华尔街的金融公司势均力敌，有钱到与银行和私募股权集团抗衡，争相收购公司。
