The stellar orbital structure and the mass of the central black hole in dynamically hot galaxies are direct insights into their formation and evolution--both of the black hole and galaxy. We propose to use gas kinematics to determine the central black hole {BH} mass in NGC 3379 to high accuracy. Detailed modeling including this BH mass and previous HST and extensive ground-based data will measure the stellar orbital distribution throughout the galaxy. Recent work suggests that elliptical galaxies tend to have tangentially biased orbits near their centers, consistent with results from BH binary simulations in galaxies. However, knowledge of the central BH mass is one of the limiting factors for providing accurate measurements of the orbital structure. In addition, this data will allow us to compare the mass measured from gas to that measured from stellar kinematics using our previous analysis. An urgent need in BH physics is cross checks between gas and stellar BH masses, particularly in systems where the gas mass promises to be accurate. NGC 3379 is a rare example of a system that lends itself to this comparison. Finally, accurate BH masses are necessary ingredients to characterize the relation, if one exists, between their masses and those of the host galaxy.
