Who is the real founder of Coaching?

코칭 관련 책을 쓰면서 혼란스러운 것은
과거 학자나 전문가, 철학자 등
당신은 코칭이란 용어를 사용한 적이 없는데, 
그를 코칭의 원조라고 명명하는 것이 과연 맞는 것일까?
그의 사고 체계에 코칭 사고와 논리 틀이 있다고 해서
후세가 그를 코칭의 원조라고 칭하는 것이
맞는 것일까?

The modern coaching profession doesn't have a single "inventor" who created it overnight. Instead, it evolved over decades, drawing from psychology, sports, and business management. However, when people ask about the "real founder" of coaching, the credit is typically shared among three key pioneers who shaped it into the profession it is today:

 

1. Thomas Leonard (The Architect of the Profession)

Thomas Leonard is widely considered the founding father of modern professional coaching, particularly life and business coaching. Before Leonard, coaching existed as a loose concept, but he formalized it into a distinct profession.

• He founded Coach U in 1992, one of the first formal coach training programs.

• He established the International Coach Federation (ICF) in 1995, which remains the leading global organization for coaching standards and credentialing.

• He later founded CoachVille and the International Association of Coaching (IAC).

 

2. W. Timothy Gallwey (The Philosophical Pioneer)

If Leonard built the professional structure, Timothy Gallwey laid the foundational philosophy. A Harvard academic and tennis captain, Gallwey published The Inner Game of Tennis in 1974.

• He introduced the revolutionary concept that "the opponent within one's own head is more formidable than the one on the other side of the net."

• His approach shifted the focus of instruction away from fixing technical errors and toward facilitating self-awareness, reducing self-doubt, and unlocking a person's natural potential. This "Inner Game" methodology became the psychological bedrock of modern coaching.

 

3. Sir John Whitmore (The Corporate Catalyst)

Sir John Whitmore took Gallwey's "Inner Game" concepts, which were initially focused on sports, and successfully adapted them for the corporate and business world.

• He is famous for co-creating the GROW model (Goal, Reality, Options, Will/Way Forward) in the 1980s, which remains one of the most widely used coaching frameworks globally.

• His 1992 book, Coaching for Performance, helped legitimize coaching as an essential tool for organizational leadership and management.

 

In Summary:

If you are looking for who organized coaching into a formal, credentialed industry, it is Thomas Leonard. If you are looking for the original thinker whose philosophy made modern coaching possible, it is Timothy Gallwey. If you are looking at who brought it into the boardroom, it is Sir John Whitmore.

There is no single “real founder” of coaching. The accurate answer depends on what kind of coaching you mean.

Best historical answer:

 

1. Professional / life coaching:
The strongest claim goes to Thomas J. Leonard. He founded Coach U in 1992, one of the first professional coach-training schools, and later founded the International Coach Federation (ICF), which became the major global professional coaching body. ICF itself identifies Leonard as its founder.  

 

2. Modern performance / business coaching:
The roots usually point to W. Timothy Gallwey and Sir John Whitmore. Gallwey’s The Inner Game of Tennis was first published in 1974 and introduced ideas about performance, attention, interference, and self-directed learning that strongly shaped modern coaching.   Whitmore then helped translate these principles into workplace and leadership coaching, especially through Coaching for Performance and the GROW model.  

 

3. Coaching psychology / evidence-based coaching:
For coaching psychology, Anthony Grant and Michael Cavanagh are central figures. They established the world’s first university-based Coaching Psychology Unit at the University of Sydney in 2000.  

 

So, if someone asks, “Who founded coaching?”, the most precise answer is:

Thomas J. Leonard is often regarded as the founder of professional coaching as an organized modern profession, while Timothy Gallwey and John Whitmore are foundational figures in modern performance and business coaching. Coaching itself, however, has no single founder.

 

For scholarly writing, I would avoid saying “the founder of coaching” without qualification. I would write: “Thomas J. Leonard, widely regarded as a founding figure of the modern professional coaching industry…” or “Gallwey and Whitmore were seminal figures in the emergence of performance-oriented coaching.”
