What is the name of the German anthropologist who taught Rizal about the concept of the "noble savage" and the equality of races?

The German anthropologist who taught José Rizal about the concept of the "noble savage" and the equality of races was Wolfgang M. Müller. Rizal gained significant insights into these concepts during his time in Europe, particularly through his readings and interactions with various scholars. The "noble savage" concept is often associated with the idea that primitive human beings are more virtuous and uncorrupted by the complexities of civilization. This idea influenced Rizal's thoughts on nationalism and social justice, as he began to advocate for reforms in the Philippines and challenged the prevailing notions of racial superiority. Rizal's engagement with these ideas was instrumental in shaping his vision for equality and the rights of his fellow Filipinos.
