According to this site, Kurosawa found the gibberellin. Yabuta isolated it from the sample and named gibberellin. This is a better source of information than the first one I listed.

Answer 2

Gibberellin was first isolated in 1935 by Japanese scientist, Teijiro Yabuta (1888-1977) from the fungus Gibberella fujikuroi.Gibberellins are plant growth substances (phytohormones) involved in promotion of stem elongation, mobilization of food reserves in seeds and other processes. Its absence results in the dwarfism of some plant varieties. Chemically all known gibberellins are diterpenoid acids that are synthesized by the terpenoid pathway in plastids and then modified in the endoplasmic reticulum and cytosol until they reach their biologically-active form[1]. All gibberellins are derived from the ent-gibberellane skeleton. The gibberellins are named GA1....GAn in order of discovery. Gibberellic acid, which was the first gibberellin to be structurally characterised, is GA3. There are currently 136 GAs identified from plants, fungi and bacteria. [1].
