There are certain central truths of leadership that remain timeless. Yet, conventional wisdom doesn't always carry forward to modern times. In fact, the way we lead today is constantly changing; we're constantly learning the best way to move people toward accomplishing a common goal.

To help us navigate the ever-changing leadership landscape, there are leadership innovators that are shedding light on the ancient art of motivating and inspiring people. From advances in social sciences or neurobiology to creative ways to engage and communicate, these thought leaders are shaping how we think about--and view--leadership.

Because I didn't want this to be a rehash of the same names that everyone lists in their "Top Leader" posts, this list of leadership innovators includes some names that may be familiar to you--and some new ones. I intentionally want to shed light on--and introduce you to--the innovators doing remarkable work, and making a real difference.

Each name links to the innovator's website. I encourage you to explore their work, and learn why they made this list. I believe it will become evident that each person is doing important work to help us lead in the 21st century.

A Word about How the List Was Developed

This list of leadership innovators are authors, professors, speakers, in-the-trenches leaders, and management/leadership consultants/advisers. Through their work, they deepen our understanding of the art of leadership. Some have won awards and others have been nominated. Some advance our understanding of motivating and inspiring people to unlock their potential through their leadership roles in organizations. Many in the list have written books I have found to be both inspiring, and actionable.

While it is difficult to measure each person's impact, the list is made up of those whose efforts can at least be seen: through books, blogs, talks, or media coverage. It's for this reason that the list is alphabetical.

How the names were even considered is based on their ubiquity, message, and public acceptance. Clearly, the internet--and the availability and consistency of their message--played a powerful part in helping develop the list.
