I'll let other people speak from first hand knowledge and only mention that ADM formalism of GR is basic to most of the current work in quantum gravity and numerical GR.
http://en.wikipedia.org/wiki/ADM_formalism
==quote wikip==
The ADM formalism, named for its authors Richard Arnowitt, Stanley Deser and Charles W. Misner, is a Hamiltonian formulation of general relativity that plays an important role in quantum gravity and numerical relativity. It was first published in 1959.[2]

The comprehensive review of the formalism that the authors published in 1962[3] has been reprinted in the journal General Relativity and Gravitation,[4] while the original papers can be found in the archives of Physical Review.[2][5][6][7][8][9][10][11][12]

In other words ADM is huge. If I understand correctly, the Ashtekar variables formulation of GR, which is the basis of LQG and probably a bunch of other approaches to QG, derives from ADM.
You have indicated other claims to fame besides ADM, but ADM by itself seems to provide Deser a permanent place in history.

https://arxiv.org/pdf/2503.09804 From the abstract: ... Our derivation uses both EE and the Newtonian approximation of EE in Part I, to describe semi-classically in Part II the advection of DM, created at the level of the universe, into galaxies and clusters thereof. This advection happens proportional with their own classically generated gravitational field g, due to self-interaction of the gravitational field. It is based on the universal formula ρD =λgg′2 for the densityρ D of DM...
Many of us have heard of "twistors", arguably Roger Penrose's biggest contribution to theoretical physics. Twistor space is a space which maps nonlocally onto physical space-time; in particular, lightlike structures in space-time, like null lines and light cones, become much more "local" in twistor space. For various reasons, Penrose thought that twistor space was possibly a more fundamental arena for theoretical physics than space-time, and for many years he and a hardy band of mostly...
