Charles Baeyertz was educated at Prince Alfred College, Adelaide, and attended the London College of Music. Baeyertz moved with his family to Dunedin, New Zealand, in 1892, and taught languages, elocution, music and singing. He was drama critic for the Otago Daily Times and also wrote for the Otago Witness.
In April 1893, he published the first monthly number of the Triad, a journal with which he would be associated for the next twenty-two years. Baeyertz's conservative views in the arts were reflected in the pages of the Triad with many anti-modernist articles. He was supported by Frank Morton's frequent attacks on modernist poets, particularly Ezra Pound. Baeyertz moved to Wellington in 1912 and to Sydney in 1913, subsequently bringing the Triad with him to each destination.
Baeyertz was a judge of elocution and singing at many amateur competitions in Australia and New Zealand, earning a reputation for offensive remarks. He was involved in libel actions several times.
Baeyertz ended his association with the Triad in 1925 and ended his working life as a broadcaster and speech coach for the Australian Broadcasting Commission. He was also engaged as an elocution examiner at several educational institutions. Charles Baeyertz died in 1943.
