Teobert Maler, later Teoberto (12 January 1842 – 22 November 1917) was an explorer who devoted his energies to documenting the ruins of the Maya civilization.
Teobert Maler was born in Rome to German parents. His father was a diplomat for the Duchy of Baden. Maler studied architecture and engineering in Karlsruhe, then at the age of 21 moved to Vienna where he took a job with architect Heinrich von Ferstel, and became an Austrian citizen.
He was eager to see more of the world and went to Mexico as a soldier with Emperor Maximilian. He rose from Cadet to Captain. After surrendering to the Mexican Republican forces, Maler opted to stay in Mexico rather than being exiled back to Europe. Maler later obtained Mexican citizenship and changed his first name to "Teoberto", more easily pronounced in the Spanish language.
Maler developed interests in photography and in the antiquities of Mesoamerica. In 1876 he made detailed photos of the structures at Mitla. In the summer of the following year he moved to San Cristóbal de las Casas, and in July set out to visit the ruins of Palenque. While several accounts of the site had been published by this time, it was still little visited, and Maler needed to employ a team of the local Indios to open a path to the ruin with machetes. He spent a week at Palenque, sketching, measuring, and photographing the site, and became aware that earlier published accounts were inadequate, and that most earlier visitors had limited their descriptions to only a portion of the buildings observed there. While Maler was there another visitor came to the ruins, Gustave Bernoulli, a Swiss botanist who shared his interest in Maya sites, and had recently made a visit to Tikal. Bernoulli confirmed Maler's suspicion that there was much work that needed to be done to document the area's ruins.
