Daniel Egger was a Swiss-born engineer who worked for John Knudsen "Jack" Northrop at Lockheed on the Vega, at Avion and, when Avion was bought by United Aircraft & Transport Corporation (UATC), at Northrop Aircraft Corporation in Burbank, California. Due to circumstances beyond his control and not of his fault, he and his family were deported back to Switzerland in 1930. He maintained a correspondence with Jack Northrop throughout and, with Northrop's help, came back to the United States in 1938/39, eventually working for the Vega Airplane Company, Garret AiResearch and Northrop Aircraft Inc.

Scope and Content

The Daniel Egger papers include correspondence, printed matter, and photographs related to Daniel Egger’s career in the aerospace industry. The letters that may prove to be the most interesting in this collection are between John Knudsen Northrop and Egger regarding his immigration status. In a letter dated January 4, 1934, Northrop makes an effort to find Egger a position in Germany. He writes, “It occurs to me that with the tremendous outpouring of Jews from Germany there should be good positions for men with aeronautical experience in that country considering the large number of Jews with technical experience who were deported.” Other correspondence includes letters from Northrop's wife, Inez Northrop, and her helper, Emma Nuila, to Alexander Egger. There is also some material in Spanish where Egger spent some time in El Salvador in 1922 and 1926. The early photographs in this collection include Lockheed Aircraft Company during the Vega, Air Express, and Alpha period. Other photographs include Egger’s involvement in the Snark missile program and images of other pilots. There are also some personal photographs related to Northrop’s home, children, and Big Bear cabin. There is one large blueprint of either the Northrop Aircraft Corporation Alpha or Beta wing. Other material found scattered throughout the collection consists of newspaper clippings, greeting cards, invitations, negatives, and postcards.
The oversize folder includes ten images and photographs removed from glass frames.
Box 3 includes one address book, certificates, correspondence, ephemera, negatives, and photographs. Included is Albert Einsten's signature on a piece of paper from a conference in France, dated March 20, 1922. The flash drive contains approximately 85 GB of data and includes a detailed Excel guide, high resolution .tiff and .jpg scans of each item in the collection; including fronts and backs where necessary. The scans and information were provided by Tony Chong, Historian Emeritus, Northrop Grumman Aerospace Sector in 2019.
Cataloger's note: The EC-# was an original numbering system that was retained when the collection arrived. The EC-#s mirror the EC-#s found on the flash drive.
