Francisc Iosif Rainer (December 28, 1874 – August 4, 1944) was an Austro-Hungarian-born Romanian pathologist, physiologist and anthropologist. From an immigrant family, he earned early recognition for his experimental work in anatomy, and helped reform Romanian medical science. He spent much of his youth training himself in anatomical pathology and the various areas of natural science, gaining direct experience as a microbiologist, surgeon, and military physician. With teaching positions at the University of Iași and the University of Bucharest, where he established specialized sections, Rainer became a noted promoter of science and an innovator in his field. He notably favored and introduced the anatomical study of "functional structures", and was in particular preoccupied with issues pertaining to ontogenesis and kinesiology. An intellectual influence on several generations of doctors, his wife was Marta Trancu-Rainer, Romania's first female surgeon.
In addition to his experimental approach, Rainer is remembered as a talented pedagogue and public speaker, who took public stances in defense of his social and cultural ideals. Vilified by the far-right for his left-wing stances, he blended progressivism with genetic determinism, and, although an adept of eugenics, condemned scientific racism. He was notably involved with Dimitrie Gusti's project of rural sociology, contributing an anthropological record of several isolated villages on the Carpathian slopes. During his lifetime, Rainer also set up a large collection of craniums and skeletons, which became the centerpiece of his Bucharest anthropology department.

== Biography ==

=== Early life ===
Francisc Rainer was a native of Rohozna town, near Czernowitz, in Austrian-ruled Bukovina. His parents were Lutheran, but baptized their son Roman Catholic. His father, Gustav Adolf Ignatz Rainer, emigrated to the Romanian Old Kingdom as an employee of the Strousberg Company that built the Bucharest-Giurgiu railway, the country's first. Remaining there, he obtained a post in the administration of the national railroad company. His mother Maria (or Ana) came from a clerical family, and was a housewife. The boy received his primary education at home from his parents, later attending Saint Sava High School in Bucharest. Among the teachers who were particularly helpful was Sabba Ștefănescu in natural sciences. Rainer read extensively, teaching himself Latin and Ancient Greek, and becoming passionate about the literary works of Goethe and the philosophy of Arthur Schopenhauer. He slowly discarded the latter's influence when he discovered Heraclitus, Ernst Haeckel, and classical materialistic thought. Such works diverted him from his original goal of becoming a Catholic missionary.
In 1892, he enrolled in the medical faculty of the University of Bucharest. While still a student, Rainer was given important tasks by a professor in his histological laboratory. In 1896, he was named a junior teaching assistant in the medical clinic at Colțea Hospital; he remained there for nearly two decades. During this time, troubled by "the great issues of the Cosmos", he imposed on himself a rigorous program of study and exercise (including cycling, mountaineering, and fencing). Although struggling to make ends meet, Rainer deepened his anatomical research, closely studying human morphology, and experimented with examination techniques during autopsies, founding a Romanian Anatomical Society for the purpose of sharing results. He also attended Anghel Saligny's lectures in chemistry at the School of Bridges, worked as a chemist in Constantin Istrati's lab, then as a pathologist at the Veterinary School. He moved between Colțea, Filaret, and the school of assistant surgeons, taking part in the campaign against tuberculosis. In the summers of 1900 and 1901, he took part in an anti-cholera campaign in the Danube Delta, which also allowed him to study the native flora and fauna.
He completed his doctorate in 1903, the topic being a particular form of cirrhosis. Having performed numerous autopsies at the hospital, he made an original discovery himself; at the end of the thesis committee's debate, two of its members, Dr. Stoicescu from Colțea and Victor Babeș, extended their collegial greetings to Rainer. Aside from this pair, his professors included Alexandru Obregia, Nicolae Kalinderu, Thoma Ionescu, Gheorghe Marinescu, Ioan Cantacuzino, and Mina Minovici. Also in 1903, Rainer, recently naturalized Romanian, married Marta Trancu, an Armenian Romanian doctor who had worked with him at Colțea. They had corresponded intensely on scientific and cultural subjects, before becoming romantically involved. After completing her studies, Marta became Romania's first female surgeon. Their only child, daughter Sofia, was born on in May 1904.

During that period, Rainer made two visits to Germany. The first, in 1906, involved work at Berlin's Frederick William University in the laboratories of Fedor Krause and Oscar Hertwig, as well as a study of embryology and comparative anatomy. His animal experiments there were primarily focused on the ossification process. At the anatomical institute led by Heinrich Wilhelm Waldeyer, he analyzed the brains of individuals belonging to different races. The second visit, in 1911, involved a stop at the German Hygiene Museum in Dresden, at the anatomy institute of the University of Jena and at Leipzig. Near the trip's conclusion, while in Weimar, he visited Goethe's House.
