Nicolás Achúcarro (1880-1918), and the neuropathology laboratory he built in Washington

The Spanish neurohistologist who spent 1908 to 1910 at the Government Hospital for the Insane in Washington, organised one of the earliest laboratories for systematic neuropathology inside an American psychiatric institution, and went home to invent the tannin and ammoniacal silver method of 1911. He did not name microglia and did not define oligodendrocytes - his pupil Río-Hortega did both - and he was dead at thirty-seven.
