Solving Approach
This one works out to about 4.2 letters per word on average. Look for the shortest cipher groups first — they're the quickest way to get a toehold before tackling the longer words. Rated medium, this one asks for a bit more pattern recognition than a warm-up puzzle, but nothing that requires guesswork.
About John D. Rockefeller

He became known for his philanthropic efforts, particularly in education and medical research, leaving a legacy that extended far beyond the oil industry.
