Letter from K.A. Bauer, Carl Zeiss, Inc. to Maude Bennot, Director of the Adler Planetarium

ZPC.S2.F1.9

Letter acknowledging Bennot's comment that the Zeiss planetarium's moon image is unsatisfactory and poses questions to consider. Also discusses the Adler's need for light bulbs for the Zeiss projector and states that while Westinghouse and G.E. might have bulbs to meet Adler's needs, Zeiss bulbs are better as they were manufactured under Zeiss supervision. The letter lists out 7 bulbs of varying voltage and wattage.
