- ↑ Pawigunaan kruna aluminum warsa 1812 olih Davy sampun ngamalunin pawigunaan aluminium olih panyurat liyanan. Menawi, Davy ketah ketah kanikayang manados jadma sané ngaranin datu punika; ida pinaka jadma kapertama sané ngicain aran aluminium: Ida nganggé aluminum warsa 1808. Panyurat liyanan tan narima aran punika, ngamilih aluminium manados pagentos nyané. Cingak selantur nyané iriki.
