Life

Ludwig Mach was the eldest son of the physicist Ernst Mach and his wife Louise Marussig. From 1879 to 1883 he attended the k. k. German state high school in Prague, then studied for two years as a privateist and attended the k. k. State high school in Arnau .

Since the 1890s he continued the photographic attempts of his father and Peter Salcher . In 1892 he and his father developed the Mach-Zehnder interferometer , which was also developed independently by Ludwig Zehnder .

In 1894 he invented an aluminum alloy with 2 to 30 percent magnesium, which he called Magnalium and for which he received a patent, the marketing of which he achieved at times high income.
