Haldane 1908, still in use in all dive computers (EN/FR/ES)
[Factsheet] The 1908 publication established the first decompression model and the first diving tables, creating the concept of decompression stops based on the maximum depth reached and the dive time (which at the time was opposed to a slow and uniform ascent, independent of depth and dive time).
Bühlmann is an Haldanian set of parameters.
