    On This Day - Nov 10 : Ernst Otto Fischer was born

    He was the co-recipient of the Nobel Prize in Chemistry in 1973 for determining the structure of ferrocene (Fe(C5H5)2), a single iron (Fe) atom sandwiched between two five-sided carbon rings. There are many analogues of ferrocene, which together have led to the rapid growth of organometallic chemistry.

    On This Day - Nov 30 : Smithson Tennant was born

    He discovered iridium (Ir) and osmium (Os), the latter named for the unpleasant odour of some of its compounds (from the Greek word ‘osme’ meaning odour). He also proved that diamonds are pure carbon.
