Adolfo Omodeo. Siniscalco developed a reputation for challenging the "powers that be" with his poetry and anti-establishment views. By the time of the outbreak of World War II, a teenaged Siniscalco moved with his family to the small town of
Cava de' Tirreni, fifty kilometres from Naples, in order to escape the heavy Allied bombardments of the city and its harbour. By the age of 17, he became engaged to Emma (Emanuela) De Filippis, whom he married 8 years later.
During the war, Marcello matriculated at the

to study medicine and become a doctor, of which there was a desperate shortage. Throughout his medical studies, however, he also continued to invest in his intellectual passions. In 1943, together with his older brother Gino, he founded a cultural association and cinema group that brought many prominent intellectuals to

Eduardo De Filippo OMRI (; 26 May 1900 – 31 October 1984), also known simply as ''Eduardo'', was an Italian actor, director, screenwriter, and playwright, best known for his Neapolitan language, Neapolitan works ''Filumena Marturano'' and ...
(many of whose poems Marcello would recite in Neapolitan dialect by memory throughout his life).
Although he never pursued a career as a practising doctor, it was his training in biology, and the tutelage of his mentor Professor
Giuseppe Montalenti during the late 1940s and early 1950s at the
Stazione Zoologica at the Naples Aquarium, that enabled Marcello to discover the nascent field of genetics. As a part of his doctorate in 1948, he completed a study on the relationship between nucleic acid metabolism and protein synthesis carried out in tiny crustaceans. This was one of the earliest known works attempting to understand the link between

International career
Recognizing that progress in his field of genetics was advancing faster abroad than in Italy, Marcello interspersed his career with international appointments. His first such adventure entailed moving to a smoggy London in 1952 at age 28 as a British Council Research Fellow at the Galton Laboratory,

, where – despite his beginner’s English - he was able to study alongside well-known researchers including
J. B. S. Haldane,
Lionel Penrose,
Cedric Smith and
Harry Harris. Due to his charm and numerous non-scientific interests, he also freelanced as a radio show host, which earned him ten guineas per hour, a multiple of his British Council fellowship. His roommate of the time, somewhat jealous of Marcello’s newfound cash flow, commented jokingly that he "knew of only one other profession which paid a similar hourly wage!"
Upon his return to Italy from the UK, Siniscalco's first three children were born: Raffaello (1949), Antonella (1951) and Federico (1956). Like many Italian professors of the mid-twentieth century, Siniscalco became a member of the establishment and a pillar of his community. However, due to early trips to symposia abroad to institutions such as

By 1967/8, however, it was on the other side of the Atlantic where genetics was making the greatest advancements. Marcello therefore accepted an invitation as Visiting Professor to the

techniques, with methods of reliably identifying chromosomes, means that crude mapping at this level is being greatly speeded up, and that the position of genes within chromosomes is now being tackled. Marcello Siniscalco is perhaps the leading exponent of this latter craft.
Marcello met his second wife, Marina Wehde Kulbach, at an international conference in Berlin in 1971. Within two years, Marina joined Marcello in New York, along with her mother and young daughter Anja, whom Marcello eventually adopted. Their son Claudio was born there in 1976.
Throughout his over 20-year career in the United States, Siniscalco made a point of returning to his native Italy every summer for research purposes, specifically to the island of Sardinia. There, he took advantage of church genealogical records, as well as high incidences of complex diseases such as

. Siniscalco would move his family from New York to Sardinia for two to three months at a time. His summers consisted of data collection, often involving convincing sceptical shepherds in isolated mountain villages to allow him to take their families’ blood samples. Being the only "doctor" within reach led to some delicate situations, such as racing a woman in advanced labour down a windy and bumpy mountain road, fearing he might have to actually deliver her baby.
Returning to Italy
In July 1989, Siniscalco returned to Italy, enticed by a government program designed to lure back the leading expatriate scientists of his generation, including contemporaries such as his close friends

. After almost 20 years of commuting to Sardinia for data collection, Siniscalco, recognized as a "world-class researcher," could finally pursue his dream to found and create a Sardinian Center for Studies of Genome Diversity in Porto Conte. He could now perform population studies of human molecular variation onsite on the island itself, rather than having to transport samples abroad. In order to maintain a link to the international community, however, Siniscalco organized close cooperation with the Imperial Cancer Research Fund Laboratory of the UK (1989–1994), where he was hosted by Sir

Siniscalco's vision was not only to improve efficiency by enabling local analysis of the Sardinian people's genome. He also sought to create a database of markers and mutations for complex diseases which could ultimately be made freely available to the general public via (then) nascent technologies such as the Internet (of which he was an extremely early adopter). Despite several entreaties and offers to explore financing from the venture capital/biotech community, and the commercial success of companies such as

Later years
During the last decade of his career, Siniscalco became a Professor of Genetics and consultant for population genomics at the
Coriell Institute for Medical Research (in Camden, New Jersey), where his vision was to "immortalize" the bulk of the many samples he had collected over the years for future generations to analyze. Subsequently, and finally, he joined
