Carl Lampland was the first to observe a comet in the infrared, a feat littleknown today because he failed to formally publish his data. I have retrievedthe radiometry of this comet, C/1927 X1 (Skjellerup-Maristany), taken in broaddaylight, from Lampland's logbook in the Lowell Observatory archives, andpresent a preliminary reduction of it here. There are similarities betweenLampland's pioneering achievement and V. M. Slipher's discovery of theredshifts of the spiral nebulae (and thus, arguably, the expansion of theUniverse). Each astronomer used state-of-the-art instrumentation, received ravereviews at American Astronomical Society meetings where their novel data werepresented, and suffered under-recognition in ensuing decades. A common threadin these poor outcomes was their lackadaisical approach to formal publication -in Slipher's case, publishing in internal or secondary outlets, and inLampland's case, not publishing at all.
