厄普顿·辛克莱(Upton Sinclair，1878年9月20日-1968年11月25日)美国作家，美国现实主义小说家。“社会丑事揭发派”(muckraker)作家。1906年发表《屠宰场》（The Jungle），描写大企业对工人的压榨和芝加哥屠宰场的不卫生情况，引起人们对肉类加工质量的愤怒，导致制订了食品卫生检查法。后以反法西斯英雄兰尼·巴德为主人公写了11本系列小说，反映1914年以来的重大事件。一生共著有小说和社会研究著作80余部。

一百多年前，美国作家厄普顿·辛克莱写了一本震惊美国的书。厄普顿·辛克莱和自己的中国同行夏衍一样，亲身到屠宰厂“潜伏”了七个星期，如实把一切可怕的事实记录下来，直接引发了美国公众对食品安全和卫生的强烈反应，也最终惊动了美国政府，直接推动了《纯净食品及药物管理法》的通过和美国食品和药品监督管理局的成立。后者在之后的百年成为美国食品安全的守护神。这种社会效果如此之好，以至于作者后来自己调侃说：“我想打动公众的心，却不料击中了他们的胃”。 这其实是一本关于命运和抗争的书。

It was four o'clock when the ceremony was over and the carriages began to arrive. There had been a crowd following all the way, owing to the exuberance of Marija Berczynskas. The occasion rested heavily upon Marija's broad shoulders—it was her task to see that all things went in due form, and after the best home traditions; and, flying wildly hither and thither, bowling every one out of the way, and scolding and exhorting all day with her tremendous voice, Marija was too eager to see that others conformed to the proprieties to consider them herself. She had left the church last of all, and, desiring to arrive first at the hall, had issued orders to the coachman to drive faster. When that personage had developed a will of his own in the matter, Marija had flung up the window of the carriage, and, leaning out, proceeded to tell him her opinion of him, first in Lithuanian, which he did not understand, and then in Polish, which he did. Having the advantage of her in altitude, the driver had stood his ground and even ventured to attempt to speak; and the result had been a furious altercation, which, continuing all the way down Ashland Avenue, had added a new swarm of urchins to the cortege at each side street for half a mile.
