The Kaba meteorite is a carbonaceous chondrite which fell at Kaba, near Debrecen, Hungary, on 15 April 1857. Samples of it and the Cold Bokkeveld meteorite were examined and found to contain organic substances by Friedrich Wöhler, who inferred a biological origin. Ironically, it was Wöhler who had shown that it was possible to make organic chemicals by inorganic means. However, it was only later appreciated that complex carbon molecules can be manufactured in space by purely chemical processes.
