This is Dr. Santiago Ramón y Cajal. Like most of us, he didn’t know exactly what he wanted to “be” when he grew up. He apprenticed with a few different trades, but nothing really stuck - he had dreams of becoming an artist, but his father (a surgeon) persuaded him to pursue medicine instead. He contributed invaluable observations to science and medicine, including but not limited to: the polar properties of neurons, the contiguous nature of our nervous system, and the patterns of reinforced and continually changing (“plastic”) neuronal networks. He earned a Nobel Prize for his work, and is one of the founding fathers of neuroscience.
Obviously he had an amazing, groundbreaking career as a scientist, but what really gets me are Cajal’s artful renderings of neuronal cells. More than one hundred years later, they are still scientifically relevant, and in my opinion, haven’t lost any of their charm or elegance. He is one of my favorite neuroscientists, and if I can grow up to be 0.0001% as cool as he was, I will consider my life a success.
