Bowen's Kale
Produced by Humphry Bowen, the reference material called Bowen's Kale was used for the calibration of early scientific instruments intended to measure trace elements in the 1960s.[2]
With Peter Cawse, Bowen grew, dried and crushed a large amount of marrow-stem [[{{{1}}}]][][3] (Brassica oleracea var. medullosa) into 100 kg of a homogeneous and stable powder in 1960 that was subsequently freely distributed to researchers around the world for over two decades. This was probably the first successful example of such a de facto standard.[4] It stimulated preparation of further materials by other organizations for similar use.
