Museo de Química y Farmacia Profesor César Leyton, Science museum in Santiago, Chile

The Museo de Química y Farmacia Profesor César Leyton is a science museum in Santiago, Chile, linked to the Universidad de Chile and located on Calle Merced near Parque Forestal. Its display cases hold old laboratory instruments, pharmacy bottles, books, and documents that show how chemists and pharmacists worked in the past.

The collection began in the 1950s when Professor César Leyton started gathering historical objects from the fields of chemistry and pharmacy, first housed in a small room at the Universidad de Chile's pharmacy school. In 1987 the collection passed to a professional association, and it later became a museum open to the public.

The museum is named after Professor César Leyton, who began collecting objects related to the history of pharmacy and chemistry in Chile during the 1950s. Schoolchildren, students, and curious visitors come here today to see what these professions actually looked like in practice generations ago.

Admission is free, which makes a visit straightforward for school groups, families, and individual visitors alike. Opening hours are limited to weekdays, so it is worth checking the current schedule before heading over.

A mortar dated 1805 carries the inscription "Soy de Thomas Gonzales el boticario que mata a los buenos y enferma a los sanos, 1805". The museum also keeps a barrel used each spring for the Fiesta de la lavanda, a ceremony brought from Italy by César Leyton, in which colognes were bottled and wrapped with lilac ribbons.
