I focus on endosome-associated neurotoxicology. Ironically, however, when I went to look up which scholar discovered and named endosomes because of a random point of interest, which I had thought it was a simple enough question, I found that I couldn't find any literature documenting this at all. Eventually ChatGPT and google gemini told me it was Prof. Christian de Duve, and I do believe it was this great scholar who has made outstanding contributions to the field of organelles. But I still can't find clear evidence documenting this event. From my perspective even if Prof. de Duve's achievement in discovering lysosomes and peroxisomes is so great as to overshadow everything, it is not so great as to make it impossible to find any evidence that he was the one who discovered and named endosomes.

Maybe it's just that I was too young to have been born in the era when the stars of biology were shining, or that the Chinese community had very little to say about it. But the fact that I can't find strong evidence for this even in the English books I can find, or in Pubmed or Google searches, makes what should be a very simple question full of irony.

That's why I'm finally here to ask if scholars around the world can give me an accurate answer as to which scholar, and at what time, discovered the endosome as an organelle. Whoever he is, I offer him my highest respect.
