Aldo Perroncito (18 May 1882, Turin – 1929) was an Italian pathologist. He was the son of parasitologist Edoardo Perroncito (1847–1936). He is known for research involving regeneration of peripheral nerves, kinetic behavior of the Golgi apparatus during mitosis, and studies of pellagra.
In 1905 he obtained his medical doctorate from the University of Pavia, where he spent the following five years as an assistant to pathologist Camillo Golgi (1846–1926). During this time period he also conducted studies at the Institute of Physiology in Berlin and at the Institute of Parasitology in Paris. Afterwards he taught classes in general pathology at the University of Cagliari, returning to Pavia in 1922 as a full professor and as a successor to Camillo Golgi.
While an assistant at Pavia, he demonstrated with a severed peripheral nerve, that the stump attached to the cell body was able to survive and regenerate new branches, while its other stump, being detached from the cell body, degenerated. In 1910 he discovered that a Golgi body dissociated into a number of elongated structures during cell division. Perroncito named the split up pieces "dictyosomes".

Maurice Perrin (21 May 1875 – 18 October 1956) was a French physician and professor of medicine at Nancy.

He published over 200 articles, including his thesis in 1932 focusing on "the Alveolar echinococcosis of the liver". He became a professor of clinical medicine at Nancy in 1936.
He was promoted to the rank of colonel in the French Army Reserves in 1936.

Pachon is remembered for his work involving blood pressure and oscillometry; which is defined as the measurement of oscillations used in cardiovascular and respiratory physiology. In 1909 Pachon developed a sphygmographic oscillometer for measuring arterial blood pressure. Pachon's oscillometer was widely used by doctors and technicians during the first half of the twentieth century.
