Some may find this useful. I have been trying to collate a large historical database of scientific deception, indexed against University, corporation, person and journal.
To do this, I needed to decide what to call various corporate entities. This is hard to do, as mergers and names vary with geographic location. For example the US division of Bayer went a completely different route from the parent Bayer (which re-emerged from the death camps of IG Farben). I have (for the moment) taken some poetic license.
Anyway, here is my work-in-progress - a historical listing of pharmaceutical mergers and major subsidiaries that can be sorted by date and company. Please send along any corrections or additions.
If you want to help maintain it (or if you know of anything better along these lines) then Email me. Feel free to criticize my artwork.
