John Fraser (botanist) of botany and natural science." Species named after Fraser include, among others, "Abies fraseri" (Fraser Fir), "Magnolia fraseri" (Fraser Magnolia), and the gentianworts, "Frasera". A 50-foot Fraser Fir was used in 1998 as the U.S. Capitol Christmas Tree; the species was also used in 1974. The Fraser's Saint John's wort ("Triadenum fraseri") is named in honour of Fraser.

Fraser was an elected fellow of both the Linnean Society of London (FLS 1810)
Noble metal hassium to livermorium inclusive are expected to be "partially very noble metals"; chemical investigations of hassium and copernicium have established that they behave like their lighter homologs, the noble osmium and mercury, and preliminary investigations of nihonium and flerovium have suggested but not definitively established noble behavior. Noble metal In chemistry, the noble metals are metals that are resistant to corrosion and oxidation in moist air (unlike most base metals). The short list of chemically noble metals (those elements upon which almost all chemists agree) comprises ruthenium (Ru), rhodium (Rh), palladium (Pd), silver (Ag), osmium (Os), iridium (Ir), platinum (Pt),
