托克维尔(1805-1859)，法国历史学家、社会学家。主要代表作有《论美国的民主》第一卷(1835)、《论美国的民主》第二卷(1840年)、《旧制度与大革命〉。《论美国的民主》使他享有世界声誉。其上卷的第一部分讲述美国的政治制度，第二部分对美国的民主进行社会学的分析。下卷分四个部分，以美国为背景发挥其政治哲学和政治社会学思想。出身贵族世家，经历过五个“朝代”(法兰西第一帝国、波旁复辟王朝、七月王朝、法兰西第二共和国、法兰西第二帝国)。前期热心于政治，1838年出任众议院议员，1848年二月革命后参与制订第二共和国宪法，1849年一度出任外交部长。1851年路易·波拿巴建立第二帝国，托克维尔对政治日益失望，从政治舞台上逐渐淡出，并逐渐认识到自己“擅长思想胜于行动”。《托克维尔回忆录》是一本关于1848年法国二月革命的回忆录，对其间许多人物(比如路易·菲力浦、路易·拿破仑、阿道夫·梯也尔、路易·勃朗等)的评述十分尖锐，用语几近刻薄。可能由于这个原因，该书在作者死后34年(1893年)才首次出版。

Alexis de Tocqueville (1805-59) came to America in 1831 to see what a great republic was like. What struck him most was the country's equality of conditions, its democracy. The book he wrote on his return to France, Democracy in America, is both the best ever written on democracy and the best ever written on America. It remains the most often quoted book about the United States, not only because it has something to interest and please everyone, but also because it has something to teach everyone.

When it was published in 2000, Harvey Mansfield and Delba Winthrop's new translation of Democracy in America—only the third since the original two-volume work was published in 1835 and 1840—was lauded in all quarters as the finest and most definitive edition of Tocqueville's classic thus far. Mansfield and Winthrop have restored the nuances of Tocqueville's language, with the expressed goal "to convey Tocqueville's thought as he held it rather than to restate it in comparable terms of today." The result is a translation with minimal interpretation, but with impeccable annotations of unfamiliar references and a masterful introduction placing the work and its author in the broader contexts of political philosophy and statesmanship.
