An 89-year-old man has reached a goal he spent 20 years working toward.He earned his doctor degree and became a physicist.
Steiner values this degree because it is what he always wanted---and because he overcame health problems that could have interfered with his studies.
As a young person in Vienna，Austria，Steiner wanted to become a physicist after reading about Albert Einstein and Max Planck.
But after World War II，his mother advised him that studying medicine would be a better choice.He earned his medical degree from the University of Vienna in 1955 and moved to the United States soon after.In the U.S，he had a successful career studying blood，became a full professor and led the hematology （血液學(xué)） department at Brown's medical school from 1985 to 1994.He helped establish a research program in hematology and directed that program until he retired from medicine in 2000.
Steiner found medical research pleasing，but it was not quite the same as his interest in physics.
"It was something like a wish that was never fulfilled， that always stuck in the back of my head，" he said. "Once I'm finished with medicine，I really don't want to spend my life just sitting around and maybe doing a little golfing or doing something like that.I wanted to keep active."
At age 70，he started taking undergraduate classes at Brown University.He was planning to just take a few classes that interested him.But by 2007，he had earned enough credits to join the doctoral program.
Physics professor Brad Marston soon realized how serious Steiner was about the subject and how hard he worked. "He already had a scientific way of thinking that younger students have to develop，" Marston said. "One thing that's really true about Manfred is he perseveres."
After the university published a story about Steiner on its website，people across the U.S.contacted him to ask for advice on how to go after their dreams later in life.
He said his advice is：Do what you love to do.
