We measure the build-up of the stellar mass of galaxies from z=6 to z=1.\nUsing 15 band multicolour imaging data in the NICMOS Ultra Deep Field we derive\nphotometric redshifts and masses for 796 galaxies down to HAB=26.5. The\nderived evolution of the global stellar mass density of galaxies is consistent\nwith previous star formation rate density measurements over the observed range\nof redshifts. Ongoing research in the CFHTLS Deep Fields confirms this result\nat lower redshifts. Further, if the sample is split by morphological type, a\nsubstantial increase is seen in the number of bulge dominated galaxies relative\nto disk-dominated galaxies since z=1.\n
