Philippus Albertus Mader, surveyor, was the son of Johan Adam Mader and Catherina Anna Elisabeth Wege. He was admitted to practice as a land surveyor in the Cape Colony in August 1858. From 1873 he collected plants in the Clanwilliam area and for some years sent specimens to P. MacOwan* at Somerset East. He also corresponded with Dr W.G. Atherstone* of Grahamstown. In 1874 Mader visited the Royal Botanic Gardens at Kew, near London, and presented them with a collection of plants from Namaqualand. Other specimens collected by him are housed in the herbarium of Albany Museum, the Bolus Herbarium at the University of Cape Town, and the Compton Herbarium in Cape Town. The species Oxalis maderi was named after him by H. Bolus*.

In the General directory... for 1886 P.A. Mader was listed as a land surveyor at Tulbach. He married Sophia Bennison Earle in 1863 and later (1895) Alice Heys.
