Sir Charles Tertius Mander, 1st Baronet (16 July 1852 – 8 April 1929) JP, DL, was a Midland manufacturer (and as such Royal Warrant holder), philanthropist and public servant, of Wolverhampton, England.
He was the eldest son of Charles Benjamin Mander, of a family of early industrialists and public servants prominent in the public and civic life of Wolverhampton since 1745. He was educated at Rugby School and at Corpus Christi College, Cambridge.
Among many public offices, Charles Tertius Mander was uniquely four times mayor of Wolverhampton 1892-6; an alderman; was awarded the honorary freedom of the borough; was colonel in the Staffordshire Yeomanry (Queen's Own Royal Regiment); and the first of the family to serve as High Sheriff of Staffordshire in 1903.
He was a progressive industrialist and manufacturer as senior partner and then first chairman of Mander Brothers (1923), the family paint and varnish works founded by his great-grandfather in 1773. He was also active in many other companies, including Thomas Parker, a Midland electrical company credited with the invention of the sparking plug, the monoblock engine and the carburettor.
He was a landowner, sportsman and pioneer motorist. In 1909 he extended his house at The Mount in neo-Renaissance style to the designs of Edward Ould (of Liverpool), who also worked for his cousin Theodore at Wightwick Manor, considered one of the most notable Arts and Crafts movement houses in England.
He was created the first baronet of the Mount, Tettenhall Wood, in the Coronation honours of George V for his public services on 8 July 1911.
He married Mary le Mesurier Paint, the daughter of Canadian Member of Parliament Henry Nicholas Paint, at Halifax in 1883, and had three children.
He was succeeded in the baronetcy by his elder son, Charles Arthur Mander (1884–1951).
