Theodore William Richards, 1868-1928. Director of the Wolcott Gibbs Memorial Laboratory at Harvard University. The precision of his atomic weight determinations has never been surpassed. He discovered the anomalous atomic weights of lead from radioactive minerals. 

Electrolytic deposition was used as a qualitative analytical technique in the early years of current electricity, but it was not until 1864 that quantitative electrochemical analysis commenced with the development of electrogravimetry by Wolcott Gibbs.76,77 Electrolytic techniques of analysis were greatly refined by Edgar Fahs Smith at the University of Pennsylvania, who introduced the rotating anode and double-cup mercury cathode. Smith s book on electrochemical analysis ran to six editions.78... 

The tetraamminedinitrocobalt(lll) salts represent the second longest known case of geometric isomerism among coordination compounds. The reddish-yellow trans compounds were first prepared in 1875 by air oxidation of a solution of cobalt(II) chloride containing ammonia, sodium nitrite, and ammonium chloride by Wolcott Gibbs, who called them croceo salts. The brownish-yellow cis compounds were first prepared in 1894 by reaction of tetraamminecarbonato-cobalt(III) salts with sodium nitrite by Jorgensen, who called them flavo salts. The two series correspond completely to the bis(ethylenediamine)dinitrocobalt-(111) salts. 

He points out that electrolytic deposition was recommended as a qualitative test for copper in 1800. The first electrogravimetric determinations were reported by Wolcott Gibbs in 1864. By a remarkable coincidence, the German industrial chemist C. Luckow reported similar investigations in 1865, indicating that he had practiced electrogravimetry since i860. Szabadvary does not mention the major contributions of E. F. 

Quantitative electrochemical analysis was not introduced, however, until 1864, when electrogravimetry was developed by Wolcott Gibbs 3) and C. Luckow (. The technique was further studied by a...
