Extragalactic low-mass X-ray binaries {LMXBs} can constrain galaxy histories, but we must first understand whether LMXBs present in the fields of galaxies were formed primordially in situ or dynamically in globular clusters {GCs}. We propose 8 orbits of HST-ACS on NGC1023, one of the nearest, massive lenticular galaxies, which will complement 192 ks of ACIS-S observations. We will detect 70 Field-LMXBs and 400 stellar clusters. Our comparison of the spatial distributions of field-LMXBs, GCs, and field stars in NGC1023 will constrain the origin of field LMXBs. Our observations will also perform the most complete census of diffuse star clusters {DSCs} to date. By probing the connection of DSCs to LMXBs, we will also test the dynamical formation model of LMXBs in stellar clusters.;
