戴尔·卡耐基（Dale Carnegie，1888年11月24日—1955年11月1日），被誉为20世纪人类最伟大的人生导师，也是著名的成功学大师，美国现代成人教育之父，人际关系学鼻祖，美国著名的心理学家和人际关系学大师，西方现代人际关系的奠基人。他的一生就像美国历史上最伟大的总统林肯一样，在平凡中创造了不平凡。主要代表作有《人性的优点》《人性的弱点》《沟通的艺术》《卡耐基人际关系学》《语言的突破》《演讲与口才》等。其作品一经问世便受到广大读者的喜爱和追捧，并被翻译成几十种文字在全球热销。如同每个奋斗者一样，卡耐基的一生也历经坎坷。从不同阶段的生活层面上，他最大的收获就是看到人们不断生活在忧虑、恐惧与无力改变现状的恶性循环中。后来他在青年会得到了一个夜大讲师的机会后，便开创了公开演说的课程，积累下来的成果就是“卡耐基训练”的蓝本。之后，他致力于影响别人、改变别人的教育事业。
