By 1938, Dr. Constant Janssen's business, which involved importing and distributing products from Gedeon Richter, a Hungarian pharmaceutical company, had grown significantly. This growth led Dr. Janssen to give up his medical practice and focus entirely on the business.

In 1948, at the age of 21, Paul Janssen took a leave from medical school to spend six months in the United States. During this time, he continued his studies at prestigious institutions like Cornell Medical School, Harvard, and the California Institute of Technology, and also visited companies to observe pharmacological research.

Dr. Paul Janssen completed his Ph.D. in Medicine at the University of Ghent, Belgium in 1951.

Throughout the history of Janssen Pharmaceutica N.V., Dr. Paul Janssen and his team of scientists discovered more than 80 medicines, several of which were groundbreaking and significant in the field of medicine.

In 1954, Dr. Paul Janssen realized his dream by establishing his lab in Turnhout, Belgium.

In 1955, Janssen's laboratory successfully launched ambucetamide, a highly effective antispasmodic drug for treating menstrual pain. This marked the first major success for Janssen's company.

In 1956, Dr. Paul Janssen obtained his Ph.D. in Pharmacology at the University of Ghent, Belgium.

On April 16, 1957, Paul Janssen married Dora Arts. This marked an important personal milestone in his life.

On February 11, 1958, Paul Janssen developed haloperidol, a significant advancement in the treatment of schizophrenia. This discovery revolutionized the field of psychiatry.

Haloperidol, a widely used drug for the treatment of psychoses, was synthesized on February 15, 1958, by Paul Janssen and his team. It became one of the most extensively used drugs worldwide in the field of psychiatry.

In 1959, Paul Janssen synthesized the potent opioid fentanyl, based on his studies of meperidine. This marked a crucial milestone in the field of pain management and anesthesia.

In 1960, Janssen developed fentanyl, a highly potent opioid that transformed anesthesia and pain treatment, becoming widely used for surgical anesthesia and chronic pain management.

On October 24, 1961, a merger took place between Janssen Pharmaceutica, the Belgian subsidiary, and Johnson & Johnson, an American Healthcare Company. This merger allowed the Belgian subsidiary to retain its identity and independence within the international group.

In February 1962, Paul Janssen decided to merge his independent research lab with Johnson & Johnson, leading to the formation of the Janssen Pharmaceutical Companies of Johnson & Johnson. This merger marked a significant milestone in the history of pharmaceutical research and development.

On February 10, 1964, the name of the Belgian subsidiary of Johnson & Johnson was officially changed to Janssen Pharmaceutica N.V. This name change marked a significant milestone in the company's history.

In 1985, Janssen established the first Western pharmaceutical factory in the Shaanxi province of China. This facility marked a significant milestone in the global expansion of Janssen Pharmaceutica.

In 1988, Janssen's Australian operations merged with Cilag to establish Janssen-Cilag Pty Limited, enhancing their search for innovative solutions to improve patients' lives.

In 1989, Dr. Paul Janssen reflected on his decision to establish an independent research lab, deviating from his father's business. This move showcased Dr. Janssen's innovative thinking and marked the beginning of his impactful contributions to the field of pharmaceuticals.

Paul Janssen became a member of the Pontificial Academy of Sciences in 1990. This prestigious membership reflected his contributions to the field of science and his recognition among peers.

In 1992, Dr. Paul emphasized the importance of independence for each company within the group after the merger with Johnson & Johnson. His legacy continues at Janssen Pharmaceutical Companies of Johnson & Johnson, with a focus on advancing healthcare.

In 1993, Dr. Paul's quotes were published by Janssen Pharmaceutica in an English text. The quotes emphasize the importance of an open mind, self-belief, and intellectual stimulation in research work.

In 1995, Janssen and Lewi co-founded the Center for Molecular Design, focusing on the development of anti-HIV compounds like diarylpyramidines. This initiative showcased Janssen's commitment to innovative pharmaceutical research.

In the early Spring of 2002, Paul Janssen attended a meeting in Rouffach, France, near the Swiss and German border. The meeting aimed to reconstruct the history of psychopharmacology, and Paul shared his insights and contributions to the field.

Paul Janssen passed away unexpectedly at the age of 77 on November 11, 2003, during a visit to Rome. His contributions to pharmaceutical science and research left a lasting legacy in the field.

The article 'A Personal Perspective on Dr. Paul Janssen' was published in the Journal of Medicinal Chemistry in 2005, providing insights into Dr. Paul Janssen's work and impact.

In 2007, a publication titled 'Successful Pharmaceutical Discovery: Paul Janssen’s Concept of Drug Research' was released in the R&D Management journal, highlighting Dr. Paul Janssen's innovative approach to drug research.

A tribute to Dr. Paul A. J. Janssen was published in Anesthesia & Analgesia in February 2008, recognizing his contributions as an entrepreneur, scientist, and his impact on anesthesiology.

In 2012, the U.S. FDA approved bedaquiline, a compound developed by Janssen Pharmaceutica researchers, for adult TB patients. This marked a significant achievement in the treatment of multi-drug resistant tuberculosis.

A medicine for multidrug-resistant tuberculosis, a condition that was difficult to treat, was approved in the United States in 2012 and in the European Union in 2014. This medicine was initially researched by Dr. Paul Janssen and later developed by a Janssen research team.

Eight medicines developed by Janssen are included in the World Health Organization's List of Essential Medicines.
