About: Mathew Evans

An Entity of Type: Person100007846, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Matthew Evans is one of two Canadians who developed and patented an incandescent light bulb, on July 24, 1874, five years before Thomas Alva Edison's U.S. patent on the device. Evans, from Toronto, Ontario, and his friend Henry Woodward, made the light bulb by sending electricity through a filament made of carbon. The two men had patented it but did not have enough money to develop their invention, so they sold their US patent 181,613 to Thomas Edison for US$5,000 ($US 100,000 in 2006 dollars). They also granted Edison an exclusive licence to their equivalent Canadian patent.

dbo:abstract
  • Mathew Evans estis kanada inventisto kaj grava pioniro en la disvolvigo de la inkandeska lampo, nome ampolo. Li estis unu el la du kanadanoj kiuj disvolvigis kaj patentis la inkandeskan lampon, la 24an de julio, 1874, nome kvin jarojn antaŭ la usona patento de Thomas Alva Edison pri la aparato. Evans, el Toronto, Ontario, kaj lia amiko Henry Woodward, faris ke la ampolo funkciu per sendado de elektro tra filamento el karbono. La du viroj estis patentintaj ĝin sed ili ne havis sufiĉan monon por disvolvigi sian inventon, kaj tiele ili devis vendi sian usonan patenton 181,613 al Thomas Edison por 5,000 usonaj dolaroj (100,000 en dolaroj de 2006). Ili ankaŭ garantiis al Edison ekskluzivan permesilon por sia ekvivalenta kanada patento. (eo)
