I was actually a big fan of Kip Thorne (25 years ago) until I read that wikipedia article about threading a non-traversible wormhole with negative energy exotic matter in order to make it traversable. It just totally tore it for me; his credibility was replaced by one of his traversable wormholes.
So that I don't come off sounding like Louis Savain (who hates basically everyone in physics), I'm going to go out on a limb and list the physicists and physics texts for whom /which I have a great deal of respect and admiration, in no particular order:
Galileo (managed to work out t^2 dependence of gravity acceleration)
Isaac Newton (obviously)
Mendeleev (periodic table of the elements- at first not so popular, but excelled in an area Newton had no clue about)
Niels Bohr (sometimes abrasive, but effective physics style)
Albert Einstein (almost always right; the genuine article)
Kurt Gödel (many viewed him as a one trick pony, without too many variations on his most famous work, but it was a very good one)
Enrico Fermi (in many ways, a man far ahead of his time)
Emmy Noether (identified conservation laws associated with gauge theory and Lagrangian / Hamiltonian dynamics)
Paul Dirac (brilliant and edgy, not afraid to go where no theorist has gone before)
Resnick and Halliday (college physics textbook for decades)
Thomas, Calculus and Analytic Geometry, any edition (vector calculus textbook for decades)
Edward M. Purcell (Nobel Laureate for MRI technology, author of Berkely Physics Vol II- Electricity and Magnetism)
Any other 20th century Nobel Laureate for physics, and there are a lot of those too numerous to name
John D. Nolan (university of Pittsburg)
Richard Feynman (I have all of his lecture series books, and an audio book with several recorded lectures which I treasure)
Wolfgang Pauli (brilliant, but could not seem to get along with a lot of his colleagues)
Wilhelm Röntgen (the identification of the atomic nucleus with crude equipment)
Nikola Tesla (a better man than Edison ever was, and was kind to animals, especially pigeons)
Max Planck (needs no explanation)
Werner Heisenberg (uncertainty principle genius)
Robert Townsend (laser optics pioneer)
Carroll O. Alley (first aircraft/atomic clock verification of GR, now key to GPS-- almost my physics mentor)
Arthur C. Clarke (invented geostationary satellites, launched my engineering career doing Intelsat R&D)
Bill Phillips (NIST, atomic clocks)
Any physicist associated even peripherally with the Large Hadron Collider, which includes our own rpenner
Carl Sagan (needs no intro, and the ONLY cosmologist other than Einstein on this list)
Claude Shannon (information theory)
Stephen Hawking (needs no intro)
Roger Penrose (occasionally wrong, but so what?)
Phillip Morris (diminuative physicist of the 1970s)
Vera Rubin (astrophysicst, friend of a number of close friends)
Neil De Grasse Tyson (needs no intro)
Bill Nye (undeniably belongs here)
Michau Kaku (my kind of physics nut ball)
Ray Davis (early neutrino detector, Nobel Laureate, friend of a friend)
Sean Carroll (even though badly influenced by Kip Thorne, is still a first-rate physicist from Cal Tech)
Bolzman (thermodynamics/entropy pioneer)
Irwin Schrödinger (didn't deserve the grilling Bohr afforded him)
John Archibald Wheeler (together with Taylor, authored 'Spacetime Physics', one of my favorite supplemental relativity textbooks from college.
Minkowski (because no one should be on the "bad" list for making what could have been an honest misapplied math mistake)
George Gamow (1, 2, 3, Infinity)
Martin Gardner (Scientific American)
Douglas Hofstadter (Gödel, Escher, Bach, the Eternal Gold Braid, Scientific American)
Jearl Walker (Flying Circus of Physics, Scientific American)
And my much shorter (but growing) list of "no, gracias" physics cranks;
David de Hilster ('Autodynamics lunatic - relativity with only ONE observer)
Louis Savain (anti-physics curmudgeon from Usenet)
Archemedes Plutonium (restaurant bus boy at Stanford in the early days of Usenet pretending to be a physics guru)
John Doan (endless internet rant about the twin paradox in the internet)
Anyone or anything associated with Metapedia (Neo-Nazi version of Wikipedia, Internet central Einstein haters club)
Anyone or anything that suggests Einstein was wrong about his SINGLE assumption to create relativity.
Kip Thorne (don't get me started)
Edward Witten (so honored for string 'M' theory arrived at by means of committee consensus)
Brian Greene (should have stuck with a sequel to "Last Mimsy" rather than embarrass himself on PBS.)
The Bogdanovich Brothers (switched from cosmology to Botox, but their paper, although trash, was never actually refuted by means of science peer review).
No one on Sciforums so far.
