How to Invest Money by George Garr Henry is a concise and practical guide for investors who seek a foundational understanding of sound investment principles. Originally published in the early 20th century, this timeless work remains relevant for readers navigating the complex world of financial markets today. With clarity and realism, Henry outlines the general principles of wise investment in the opening chapter, emphasizing safety, income, and marketability as cornerstones of intelligent decision-making. He then dives into detailed explanations of various fixed-income securities, including: Railroad Mortgage Bonds and Railroad Equipment Bonds, which were cornerstones of industrial-era infrastructure investment. Real-Estate Mortgages, exploring both their risks and appeal as income-generating assets. Industrial Bonds and Public-Utility Bonds, offering insights into corporate debt instruments and regulated sectors. Municipal Bonds, prized for their tax advantages and low default risk. In the later chapters, Henry provides a measured discussion of stocks, carefully distinguishing between speculation and investment. He concludes with a helpful overview of market movements, giving readers tools to recognize trends and make informed timing decisions. Henry’s style is accessible, educational, and geared toward the prudent, long-term investor rather than the speculator. His focus on stability, clarity, and strategy over hype and risk makes the book especially valuable for beginners or conservative investors seeking to build wealth steadily and securely.
