Wallace D. Wattles (1860-1911) was an American author and early pioneer of the New Thought movement, best known for his influential work The Science of Getting Rich (1910). Long before mindset and manifestation became mainstream concepts, Wattles explored the relationship between thought, action, and prosperity with remarkable clarity and practicality. Raised in a modest rural environment, Wattles was driven by spiritual curiosity and a desire to understand the principles behind success and fulfillment. He studied Christian socialism, metaphysical philosophy, and emerging self-development ideas before forming a philosophy centered on one core belief: every individual has the innate ability to create a meaningful and abundant life by thinking and acting in alignment with their vision. His most notable works, The Science of Getting Rich, The Science of Being Well, and The Science of Being Great, present a simple but powerful framework. Wattles taught that creative thought surpasses competition, purposeful action produces results, and sustained faith is essential for personal growth and well-being. Though not widely recognized during his lifetime, Wattles' ideas went on to influence later thinkers such as Napoleon Hill, Bob Proctor, and Rhonda Byrne.

Byrne later cited The Science of Getting Rich as a key inspiration for The Secret, expanding Wattles' reach to a global audience. Wallace D. Wattles passed away in 1911, shortly after publishing his most famous work. Today, his teachings continue to guide readers toward intentional living, abundant thinking, and aligned action.
