Hilda Villegas Castrejón (26 February 1931 Mexico City – 1 August 2012) was a Mexican surgeon and a pioneer in electron microscopy. She was a member of the Mexican Academy of Surgery.

Biography

Hilda's father, Andrés Villegas Reyes, was a medical surgeon graduated from "Escuela Medico Militar (S.D.N.)" and radiologist. She graduated in 1955 as a medical surgeon from the Faculty of Medicine of the National Autonomous University of Mexico (UNAM). She earned a pathology fellowship at Presbyterian / St. Luke's Medical Center and Columbus Hospital in Chicago. She earned a doctorate in medical sciences from the Free University of Berlin.

In 1970, she specialized in electron microscopy at the Free University of Berlin, and became a pioneer in the use of this technology in Mexico at medical institutions such as the Centro Médico Nacional Siglo XXI, the National Institute of Perinatology, and the National Institute of Rehabilitation (INR). Villegas was in charge of founding the electron microscopy sections, and at the INR she held the position of research director.

In 1990, she became the first woman to enter the Mexican Academy of Surgery as an expert in morphology. Villegas was a tenured professor at the UNAM School of Medicine.
