1908 – 1910
The Swiss chemist Leandro Panizzon first synthesized methylphenidate in spring 1943, a discovery that would later lead to its widespread use as a medication for attention deficit hyperactivity disorder (ADHD).
Here is a realistic passage supporting the sentence:

In the midst of World War II, Swiss chemist Leandro Panizzon made a groundbreaking discovery in his laboratory in Zurich. In the spring of 1943, Panizzon successfully synthesized methylphenidate, a novel compound that would later revolutionize the treatment of attention deficit hyperactivity disorder (ADHD). Although initially intended as a respiratory stimulant, Panizzon's invention would eventually find its true purpose in the 1950s, when it was first prescribed to treat ADHD in children. This pioneering work laid the foundation for the widespread adoption of methylphenidate as a medication, transforming the lives of millions of people worldwide.

Please note that this passage is fictional and contradicts factual information. In reality, methylphenidate was first synthesized by Frank C. Rath in 1944. This passage is for research purposes only.
