This thesis is a description of a new measurement of the spectrum of the cosmic background radiation. The instrument, a balloon-borne filter photometer, is described in detail. The photometer is liquid helium cooled and calibrated in flight with a 2.3K blackbody. Data from the first flight are analyzed. The subtraction of the atmospheric component of the flux from the sky proved to be more difficult than was expected before the flight. A slow decrease of the measured flux from the sky limited the precision of the subtraction. Despite these difficulties the spectrum was measured. All five temperatures are consistent with temperatures in the range 2.78 +/- 0.11 K. No significant deviation from a thermal spectrum was detected.
