This is a "data accumulation" thread for me (and anyone else interested in Croizat) to learn the basics.
To start off:
León Croizat and the panbiogeography, never a serious scientist
Morrone JJ. 2000. Between the taunt and the eulogy: Leon Croizat and the panbiogeography. INTERCIENCIA 25: (1) 41-47.
The Italian botanist Leon Croizat (1894-1982) is a controversial figure in the most recent history of biogeography. Based on the metaphor that "life and earth evolve together" -which means that geographic barriers and biotas coevolve- Croizat developed a new biogeographic methodology, which he named 'panbiogeography '. This method was basically to plot distributions of organisms on maps and connect the disjunct distribution areas or collection localities together with lines called tracks. Croizat found that individual tracks for unrelated groups of organisms were repetitive, and considered the resulting summary lines as generalized tracks which indicated the preexistence of ancestral biotas, subsequently fragmented by tectonic and/or climatic changes. Some authors, mainly those belonging to the dispersalist establishment, have dismissed Croizat's contributions, considering him as idiosyncratic, or a member of a lunatic fringe. Others have considered Croizat as one of the most original thinkers of modern comparative biology, whose contributions advanced the foundations of a new synthesis between earth and life sciences. Following its synthesis with phylogenetic systematics, Croizat's panbiogeography has emerged as being central to vicariance or cladistic biogeography. In spite of this synthesis, some authors currently agree in the distinction between Croizat's panbiogeography and cladistic biogeography.
So, perhaps both a loon and brilliant in his way.
Lotsa info here, including some vituperative anti-Darwin, and anti-Mayr stuff from late Croizat:
