Pietro Bertarelli
A Lasting Influence

Pietro Bertarelli was a key figure in the evolution of Serono, whose leadership helped transform a modest pharmaceutical company into a scientifically ambitious enterprise.Born in Italy in the early 20th century, Pietro entered the healthcare industry during a time of profound transformation in Europe. In1935, he was appointed Managing Director of Serono, then a small but pioneering firm focused on hormone-based therapies. With clarity of vision and a strong sense of purpose, Pietro laid the groundwork for what would eventually become a global biotechnology company.

Under Pietro’s direction, Serono made major strides in the extraction and clinical application of human gonadotropins, leading to the development and eventual commercialisation of Pergonal, a groundbreaking fertility treatment. He was instrumental in steering the company through decades of economic and scientific change, always balancing scientific integrity with sound business practice. His leadership was marked by a patient, long-term approach, which allowed Serono to remain at the forefront of its field while building the technical ando rganisational capacity for future growth.
