Recent observations of UGC4879 with the Advanced Camera for Surveys on the Hubble Space Telescope confirm that it is a nearby isolated dwarf irregular galaxy .
We measure a distance of 1.36 \pm 0.03 Mpc using the Tip of the Red Giant Branch method .
This distance puts UGC4879 beyond the radius of first turnaround of the Local Group and \sim 700 kpc from its nearest neighbor Leo A .
This isolation makes this galaxy an ideal laboratory for studying pristine star formation uncomplicated by interactions with other galaxies .
We present the star formation history of UGC4879 derived from simulated color-magnitude diagrams .
