Robert Harper

Died 12 May 1946 at age 84 (born 21 Jan 1862). Robert Almer Harper was an American botanist who studied the cell (cytology) in fungi. He trained with leaders in the fields in Germany for his Ph.D. Harper studied the multinucleate cell of the ascus, and how the fungus ascospore developed. The puzzle he addressed was the so-called “free cell formation” whereby eight nuclei could each cut out its own share of cytoplasm to form eight apparently equal, uniformly marked, sexually-produced spores in the ripe ascus of fungi in the class Ascomycetes. In experiments he carried out in the 1920s, while chief of the scientific directors of the New York Botanical Gardens, Harper sought improved methods of treating diseased plants. His limited publications represent only such material that he felt was important to contribute, yet he was regarded as among the great research botanists in his time.«
