WISNIAK, Jaime. Edward Charles Howard: Explosives, meteorites, and sugar. Educ. quím [online]. 2012, vol.23, n.2, pp.230-239. ISSN 0187-893X.

To Edward Charles Howard (1774-1816), a self-educated scientist without formal education in chemistry, we owe the (accidental) discovery of mercury fulminate, the finding that meteorites contain nickel and have a composition different from any material originated in the earth, and the design of the vacuum evaporator and other accessories that resulted in a substantial improvement in the economic balance of sugar production.

Keywords : Fulminates; meteorites; nickel; vacuum evaporation; sugar.
