About Carnegie: Dale Breckenridge Carnegie (originally
Carnagey until 1922 and possibly somewhat later) (November
24, 1888 – November 1, 1955) was an American writer and
lecturer and the developer of famous courses in selfimprovement, salesmanship, corporate training, public speaking
and interpersonal skills. Born in poverty on a farm in Missouri,
he was the author of How to Win Friends and Influence People,
first published in 1936, a massive bestseller that remains
popular today. He also wrote a biography of Abraham Lincoln,
titled Lincoln the Unknown, as well as several other books.
Carnegie was an early proponent of what is now called
responsibility assumption, although this only appears minutely
in his written work. One of the core ideas in his books is that it is
possible to change other people’s behavior by changing one’s
reaction to them.
