Sachs at Würzburg 1871; high school teacher at Amsterdam 1871-1875; working at Würzburg on publications on agricultural plants 1875-1877; "Privatdozent" Halle 1877; lecturer (1877) and professor of botany at the University of Amsterdam 1878-1918; in retirement working on Oenothera at Lunteren 1918-1935; drew attention to the Mendel laws concurrently with C.F.J.E. Correns and E. von Tschermak (1900); visited the United States in 1904, 1906 and 1912. **Abbreviated name**: *de Vries* \[standard form in IPNI: *de Vries*\] #### Herbarium and types A herbarium of *Oenothera* mutants, was deposited in the Nederl.
