Joseph Parnes is a person, just like you and me! He is known for being a successful investor, which means he is really good at finding ways to make money by buying and selling things like stocks (which are tiny pieces of ownership in companies).
Mr. Parnes has a special way of looking at the stock market, which helps him make smart decisions about what to buy and when to sell. He studies companies and the world around us to figure out which ones are likely to do well in the future.
By being really good at this, he has made a lot of money for himself and for other people who have trusted him to invest their money.
Just like how some people are really good at sports or math, Mr. Parnes is really good at investing. But the nice thing is, you don't have to be a genius to do well with your own money. By doing some research, being patient, and never being too greedy, anyone can make smart investments and grow their wealth over time.
