Antonio Maria Valsalva

Valsalva was born at Imola. The contemporary of Isaac Newton and Johann Sebastian Bach, he was educated in the humanities, mathematics, and natural sciences. After studies of the liberal arts, he studied medicine and philosophy in Bologna. He was taught by Marcello Malpighi, who is known as the founder of microscopic anatomy. Valsalva graduated from the medical school in 1687. In 1705, he was appointed professor of anatomy at Bologna. He was later chosen as president of the Academy of the Sciences. Valsalva taught Giovanni Battista Morgagni who edited Valsalva’s complete writings and published a biography on Valsalva, both in 1740.

In 1709, Valsalva married Elena Lisi. As he lost his health, he lost his sense of smell, but he recognized the prodromal symptoms, in the form of dyslalia, of the disease that would eventually cause his death from stroke at Bologna in 1723.

Valsalva was buried in the church of San Giovanni in Monte, Bologna. The Valsalva family donated a collection of dried anatomical specimens to be used for educational purposes to the Institute of Sciences founded in 1711. The wear of this material that followed possibly inspired the work of the Bolognese school of wax modeling and the artists Ercole Lelli and Giovanni and Anna Morandi Manzolini. This new anatomic collection includes models of the heart and lungs and is today presented at the Museum of Anatomy.

Valsalva was described as a skillful surgeon and excellent physician, a meticulous anatomist with high scientific integrity, and a man of great kindness. Morgagni wrote ". . . there is nobody of those times who goes ahead of him, very few who are his equals."

Valsalva both studied and taught in the fields of science, surgery, anatomy, physiology, and psychiatry. At a young age, Valsalva had successfully removed a dog’s kidney. He opposed cauterization in the treatment of wounds, and recommended humanitarian treatment of mentally ill patients. His main interest was the middle and internal ear, including the muscles of the external ear and the pharyngeal muscles.

Valsalva named the Eustachian tube and described its function and that of its muscle. He showed the connection between the mastoid cells and the tympanic cavity, and made observations on physiologic and pathologic processes of the ear. De aure humana tractatus published in 1704 contains a description of the Valsalva maneuver and patency test of the auditory tubes.

A skilled anatomist, Valsalva conducted many autopsies on deceased patients. During the 17th century, lacking chemical tests and knowledge of disease transmission mechanisms, he sometimes tasted the fluids he encountered in cadavers in an effort to better characterize them. "Gangrenous pus does not taste good", he wrote, "leaving the tongue tingling unpleasantly for the better part of the day."[2]

The Valsalva device is a device used in spacesuits to allow astronauts to equalize the pressure in their ears by performing the Valsalva maneuver inside the suit without using their hands to block their nose. It has also been used for other purposes, such as to remove moisture from the face.[3]
