Humboldt is a very fascinating character, who sadly is often overlooked. If anyone is interested in learning more about him, I strongly recommend this biography by Andrea Wulf: https://amzn.to/2KWiy36
Not everything named "Humboldt" is Alexander. For example, the Humboldt University Berlin (ca. 33,000 students) is named after both brothers, and it was Wilhelm who helped to create it.

I'm quoting a few sentences here because this Humboldt brother likely is much less well-known here:
> He is especially remembered as a linguist who made important contributions to the philosophy of language, ethnolinguistics and to the theory and practice of education. In particular, he is widely recognized as having been the architect of the Humboldtian education ideal, which was used from the beginning in Prussia as a model for its system of education and eventually in countries such as the US and Japan.
> Humboldt installed a standardized system of public instruction, from basic schools till secondary education, and founded Berlin University. He imposed a standardization of state examinations and inspections and created a special department within the ministry to oversee and design curricula, textbooks and learning aids.
> ...his fragment of a treatise on the 'Theory of Human Education', which he had written in about 1793. Here, Humboldt states that 'the ultimate task of our existence is to give the fullest possible content to the concept of humanity in our own person ... through the impact of actions in our own lives.' This task 'can only be implemented through the links established between ourselves as individuals and the world around us'
