Oleh Hornykiewicz (born November 17, 1926 – died May 26, 2020) was an important scientist from Austria, originally from Poland. He was a biochemist, which means he studied the chemical processes happening inside living things. He won the Wolf Prize for his amazing discoveries.
Hornykiewicz is best known for finding out that Parkinson's disease is caused by a lack of a chemical called dopamine in the brain. He also helped create a medicine called L-dopa, which is used to treat Parkinson's disease.

Who Was Oleh Hornykiewicz?
Oleh Hornykiewicz was born in a place called Sykhiw, which was part of Poland back then, but is now in Ukraine. He grew up to become a very respected scientist.
His Education and Career
Hornykiewicz studied at the University of Vienna in Austria. He later became the head of the Institute of Biochemical Pharmacology at this university, leading the department for twenty years.
In 1967, he also started working with the University of Toronto in Canada. He worked there for many years and was named a "professor emeritus" in 1992. This title is given to retired professors who are still highly respected for their work.
His Big Discovery: Parkinson's Disease
Oleh Hornykiewicz made a groundbreaking discovery about Parkinson's disease. This is a condition that affects how people move, making it hard for them to control their muscles.
Dopamine Deficiency
Hornykiewicz found that people with Parkinson's disease had very low levels of a chemical called dopamine in their brains. Dopamine is a "neurotransmitter," which means it's a chemical messenger that helps brain cells talk to each other. It plays a big role in controlling movement. His discovery showed that a lack of dopamine was the main reason for the symptoms of Parkinson's.
Developing L-dopa
Once he understood the problem, Hornykiewicz and his team worked on a solution. They helped develop a medicine called L-dopa. When people take L-dopa, their bodies can turn it into dopamine. This helps to replace the missing dopamine in the brain and can greatly improve the symptoms for people with Parkinson's disease. This was a huge step forward in treating the condition.
Later Life and Legacy
Oleh Hornykiewicz passed away on May 26, 2020, at the age of 93. His work changed how doctors understand and treat Parkinson's disease. Thanks to his research, millions of people around the world have been able to live better lives. He is remembered as a pioneer in the field of neuroscience and pharmacology.
