The name Helmuth is of German origin, derived from the Old High German elements 'helma' meaning 'helmet' and 'thiu' which means 'strong'. It was traditionally given as a boys' name to signify protection and strength. The name gained prominence during the Middle Ages in Germany but has since fallen out of common usage. Today, it is considered quite rare.
"Helmuth experienced a significant increase in births from 1912 onwards, peaking at 33 in 1915 and remaining high until 1920 with over 20 births each year. After 1920, the number of births fluctuated but generally decreased, reaching as low as 5 births in several years post-1940."
