J. W. Beaman, 1845-1903
"The loss of my chief topographer, Mr. Anton Schonborn, whose death occurred at Omaha after he had returned from the trip, with the notes which he had taken with zeal and ability, seemed almost irreparable. On my arrival at Washington I applied to Prof. J. E. Hilgard, the able assistant in charge of the United States Coast Survey Office, for aid in my extremity. . . . Mr. Beaman has been permitted to consult from time to time with Mr. Charles A. Schott, in the preparation of the meteorological report. I cannot too earnestly express my obligations to the officers of the Coast Survey for their aid and counsel." --F. V. Hayden 
Letter from J. W. Beaman: "I take pleasure in presenting for your consideration the report of my meteorological labors, feeling that, although it is deficient in many respects, it cannot but be of some interest in answering many questions as to the climate and elevation of the interesting region which furnished the data."
