American publisher Appleton and Company of New York City employed Oliver Byrne to edit A Dictionary of Machines, Mechanics, Engine Work, and Engineering. This massive and popular work became known as Appleton's Dictionary. Published in 1852, the book went through multiple editions. Evidence indicates Byrne edited the dictionary only through the letter F.54 A positive review of Appleton’s Dictionary concluded,55
We observe, however, with surprise, that the last number of the second volume is accompanied by new title-pages for both volumes, in which the name of the editor [Byrne] is altogether omitted. What is the meaning of this?
Appleton's Mechanics' Magazine and Engineers' Journal responded that a replacement editor was “invited by the Messrs. Appleton to take the entire charge of the editorial department of their great Dictionary, then in progress, and published as far as the letter F.”56
While living in the United States, Byrne published three pamphlets advocating Irish rebellion against British rule.57 It was said at the time that, “[Oliver Byrne] did more than any man in America to infuse into his emigrant countrymen a military spirit.”58 Byrne dedicated Freedom to Ireland to the memory of William Byrne. “Billy Byrne” of County Wicklow, Ireland died a martyr of the Irish rebellion against British rule when he was executed in 1799. It is no surprise that Oliver Byrne made no mention of his American citizenship or his Irish nationalism efforts in any of his Royal Literary Fund applications.
Copyright issues arose for Byrne both in London and the United States. Byrne’s Practical Metal Worker’s Assistant was claimed “a barefaced piracy of great portions of two volumes on ‘Turnary and Mechanical Manipulation,’ published by Mr. Holtzappel, deceased, mechanist and writer.” Its sale by Chapman was prevented in England. A newspaper covering the case reported, "The plaintiff was the widow in the executrix of her ingenious husband [Mr. Holtzappel]."59 Present day further investigation uncovered no other accusations against Byrne for plagiarism. Before Byrne completed the five-year naturalization process and became a U.S. citizen in 1854, he himself reported that publisher Henry Carey Baird “put [Byrne] into law for selling a copyright, not being a citizen.”60 Byrne later published The Young Geometrician with Chapman and Hall in 1865.61
Although it is not known if Byrne traveled to France, in 1856 he published a French guidebook on engineering and railroads entitled Vade Mecum: De L’Ingénieur de Chemins de Fer Donnant.62
After a ten year stretch residing in the United States with no Royal Literary Fund financial aid applications, in 1858, Byrne requested RLF funds63
to obtain means to bring myself, and family to England … I have no political patronage [in the United States], not having taken any part in the politics of that country … the only article of my own, in this room is a cooking stove, not yet paid for.
Before leaving the United States, Byrne made an “important metallic discovery.” He developed a process of smelting a new metal he called "Byrneore" or "Byrne metal." His metal looked like gold or silver but contained very little of either. Byrne claimed that his new alloy “would defy detection by more than nine-tenths of the dealers in wares manufactured of pure gold and silver.” Its weight and appearance were much like those of gold or silver, but at a considerably lower price. Byrneore was to be used “in the manufacture of watches, rings, pencils, spoons, forks, heads for canes, tooth-picks, pens, table sets, chandeliers, and in fact everything in which gold and silver has been used.”64 It is doubtful Byrneore ever went into commercial production.
To commemorate his new alloys, Byrne apparently commissioned medals with the profile of his wife, Eleanor Rugg Byrne, on the obverse.65 On the reverse of the medal was written “BYRNEORE GOLD 1859” with 13 stars. The medals were struck in copper plain edge, copper reeded edge (3 only), brass, and white metal.66
