Say you're looking for expert guidance on how to advance your career or build a better business. Where do you turn? There are, of course, millions of books offering advice and abstract principles on every aspect of business. But even after reading them, you may be left thinking, "That all sounds well and good, but what does that actually look like in practice?"

The place to turn, according to one entrepreneur, is biographies. On Twitter recently, founder and CTO Colin Landforce confessed that he's traded in general advice for deeper dives into the lives of past innovators. "I stopped reading business books a while ago. I'm reading history and biographies instead," he tweeted. 

Looking for titles to add to his to-read queue, Landforce asked his 20,000-plus followers to suggest great biographies and memoirs. More than 100 ideas poured in. Landforce helpfully sorted through the suggestions to weed out repetitions and self-promoters, coming up with a final tally of 43 recommendations. The full list is here or, to get you started, here are a handful of the most promising. 

1. The Tycoons by Charles R. Morris

2. The Innovators by Walter Isaacson

3. The Fish That Ate the Whale by Rich Cohen

4. American Prometheus by Kai Bird and Martin J. Sherwin

5. The Power Broker by Robert A. Caro  

Another Pulitzer Prize winner, this biography of New York politician and "master builder" Robert Moses garnered ecstatic reviews. The Sunday Times called it "simply one of the best nonfiction books in English of the past 40 years."

6. The Ride of a Lifetime by Robert Iger 

Best-selling author Brené Brown had this to say about the former Disney CEO's memoir: "I expected a book written by the person who has led Disney for decades to be defined by both gripping storytelling and deep leadership wisdom. Bob Iger delivers, and then some! The Ride of a Lifetime is leadership gold."
