Marcus Buckingham is a British-American New York Times bestselling author, researcher, motivational speaker and business consultant best known for promoting what he calls "Strengths." Basing most of his writing on extensive survey data from interviews with workers in countries around the world, he promotes the idea that people will get the best results by making the most of their strengths rather than by putting too much emphasis on weaknesses or perceived deficiencies.
Early career 
Marcus Buckingham graduated from Cambridge University with a master's degree in political science. While studying at Cambridge, he was recruited by educational psychology professor Donald O. Clifton, the founder of Selection Research, Incorporated (SRI). Clifton had co-founded SRI to develop interviews that would allow businesses to identify talents in individuals, in order to match people to the right roles.
SRI acquired The Gallup Organization in 1988, and took on the Gallup name. As part of Gallup, Buckingham became a member of a team working on a survey that measured a broad range of factors that contribute to employee engagement. Based on those surveys and on interviews with thousands of managers, Buckingham published (with coauthor Curt Coffman) First, Break All The Rules (Simon and Schuster, 1999). According to its subtitle, the book describes "what the world's greatest managers do differently" The book became a New York times bestseller and has over a million copies in print. It was also chosen by Jack Covert and Todd Sattersten as one of "The 100 Best Business Books of All Time" in their book of the same name.
Subsequent books 
Strengths became the explicit focus of Buckingham's next book (coauthored with Donald O. Clifton), Now, Discover Your Strengths, which states, "We wrote this book to start a revolution, the strengths revolution" (p. 5). Directly tied to a new Gallup personal assessment tool called "StrengthsFinder", the book presented 34 "talent themes" that characterize individuals. Those who took the assessment received a report detailing which of the 34 talent themes were their top 5 matches. In the book, the authors define a strength as "consistent near perfect performance in an activity."
- The One Thing You Need to Know
Buckingham's first solo book aimed to simplify his business advice down to "one thing" each for managers, leaders, and individual contributors. In contrast to what he would later write, in this book Buckingham contends that the advice to "discover my strengths and cultivate them" is not the most important key to individual success. Rather, he claims that the one thing a person must do in order to thrive is to "discover what you don't like and stop doing it".
- Go Put Your Strengths to Work
In this book Buckingham focused on helping individuals identify their personal strengths. Where Now, Discover Your Strengths had provided a question-and-answer assessment to describe the test taker's strengths in broad categories, Go presented a more individualized approach, asking readers to consciously observe themselves as they engaged in their work and note the specific things that made them feel strong. Settling on a definition of strengths as "those activities that make you feel strong", the book encouraged people to maximize their productivity and personal satisfaction both by cultivating their strengths and by ceasing to do what they don't like (now called "stopping your weaknesses").
- The Truth About You
This book explains the same messages as in previous books, but targeted toward high school and college students.
- Find Your Strongest Life
This book is aimed specifically at women. It was inspired by Buckingham's appearance on "The Oprah Winfrey Show."
The book generated the first substantial controversy of his career by taking as its starting point some recent survey data indicating that women had become less happy in the past 40 years. Some prominent feminists including Katha Pollitt and Barbara Ehrenreich criticized the book and a series of articles written by Buckingham in Huffington Post. Pollitt and Ehrenreich argued that the studies were flawed, that the results weren't accurately represented by Buckingham and others, and that other studies showed different results.
Find Your Strongest Life was accompanied by a new personal assessment tool called the Strong Life Test, which categorized women according to 9 "Roles," assigning a "Lead Role" and "Supporting Role" to everyone who took the assessment. The book provided general and situation-specific advice based on a person's specific Roles.
The Marcus Buckingham Company (TMBC) 
In 2006, Buckingham started The Marcus Buckingham Company (TMBC) to create management training programs and tools dedicated to promoting the strengths revolution. The company helped him to launch a coordinated series of products in conjunction with the publication of Go Put Your Strengths to Work. Most notable was Trombone Player Wanted, which expounded Buckingham's core strengths principles through a series of vignettes involving a young boy who wants to abandon playing the trombone in favor of the drums (apparently based on Buckingham's own experience in music classes as a boy). Together, the book and the film series became the basis of a TMBC workshop called Simply Strengths.
Where Simply Strengths focuses on helping individuals identify and leverage their own strengths, a second workshop, Strong Manager, aims to help managers learn "The 4 Demands of Management" and apply strengths principles to managing their employees. In 2010, TMBC also introduced a "workshop-in-a-box" titled Strengths Essentials, intended as a turnkey solution for individuals and businesses wanting to deliver their own strengths-oriented workshops.
TMBC has engaged in many corporate partnerships.
Film and television appearances 
In addition to the self-published short film series Trombone Player Wanted, Buckingham has made numerous television appearances as himself, including "The View," "I Want to Work for Diddy," "The Oprah Winfrey Show," "Good Morning America," "The Today Show," "Larry King Live," and "The Dave Ramsey Show."
