Lorentz(1853–1928)Hendrik Antoon Lorentz (1853–1928) adalah seorang fisikawanBelanda yang kali pertama me-ngemukakan tentang pemantulandan pembiasan cahaya, ditinjau dariteori bahwa cahaya termasukgelombang elektromagnetik. Teoriini dikembangkan oleh James ClerkMaxwell yang menyatakan bahwacahaya terdiri atas gelombang listrikdan gelombang magnetik dengansudut yang berbeda. Lorentz jugamemprediksi keberadaan elektron.Beliau menerima hadiah Nobeltahun 1902 dalam bidang fisika ataspenelitiannya mengenai medanmagnet. Dalam bab teori relativitas,Lorentz berjasa dalam teorinyamengenai "Transformasi Lorentz".Sumber: Science Encyclopedia, 1998
