John H. Ostrom, of Yale, was one of the most influential figures in 20th Century dinosaur paleontology.
Ostrom carried out the most extensive review of the Archaeopteryx material that perhaps has ever been executed, and was intimately involved with the discovery of two previously misidentified urvogel remains (see my primer on Archaeopteryx).
It is Ostrom's work that the post-modernist consensus on theropod phylogeny and avian origins, is largely indebted to, a fact reflected in the 1999 symposium on those very subjects, held in honor of Ostrom.

Ostrom's interest in the dinosaur-bird connection started with his study of what is now known as the Haarlem (additional info and facts about Haarlem) Archaeopteryx.
Ostrom's reading of fossilized Hadrosaurus (Any of numerous large bipedal ornithischian dinosaurs having a horny duck-like bill and webbed feet; may have been partly aquatic) trackways also led him to the conclusion that these duckbilled dinosaurs travelled in herds.

Prominent names in invertebrate paleontology include Steven Stanley, Stephen Jay Gould, David Raup, Geerat Vermeij, and Jack Sepkoski who have done much to expand our understanding of long-term patterns in the evolution of life on earth.
More modern figures in paleontology include John Ostrom, Bob Bakker and Jack Horner.
The work done in paleontology can be divided into field work, collections management, fossil preparation and systematic description of new species.

 - Camp answers Theobald -
Following the publication in 1926 of Gerhard Heilmann’s classic, The Origin of Birds, the thecodont (as opposed to theropod) ancestry of birds became a matter of textbook orthodoxy for the next fifty years.
The theropod theory of bird origins was revived in the mid-1970s through a series of papers by John Ostrom.
He detailed a number of similarities between Archaeopteryx and theropods, focusing especially on Deinonychus antirrhopus, a lightly built, 110-million-year old dromaeosaurid that he discovered in 1964.
