Rating of my work by clients:

  • “I ordered two researchers for the work in the Federal Archive. Mainly Benjamin Haas in Freiburg, who is working fast and transparently (also in costs) and is searching extensively and who was giving me helpful advices.”

Christine Holch, Copy Editor of the protestant magazine “Chrismon”

  • (…) “Parallel to his studies, he worked as a working student in the military archive in Freiburg, which is part of the Federal Archives – and wrote his master’s thesis there. That’s why he knows the archive very well and now knows exactly where to look for what. Benjamin Haas is one of the official private research services listed by the Federal Archives on its website.” Quoted from: http://gesternistjetzt.de/benjamin-haas/

The podcast for family history in National Socialism “gesternistjetzt”

  • „I needed to find the descendants of a teacher who had died during the Second World War, for the sake of a historical article I was writing. After much effort I had been able to reach his relatives in his home town, but they had lost all contact with the teachers family after the war. I had no idea how to exit the dead end. Then I requested the help of Mr. Haas. I asked him to locate documents in the Freiburg archives that may have been relevant to my search, and to see if he could locate the descendants of the teacher. There were no documents to be found in the Freiburg archives, but he was able to locate the descendants for me within just three weeks. I was amazed by his effectiveness. He is an excellent researcher, highly professional, courteous and prompt. He gets the job done. Truly magnificent!“

Stavros Theodorakis, Professor of the university Cyprus

  • Mr. Haas actively supported me in researching an uncle who died in Romania in 1944. He is a very busy researcher, but as soon as he could take on my suggestion, I felt in the best of hands with him. Competent, with an eye for the big picture, but at the same time not neglecting details, of the relevance of which the ignorant layman has no idea, he gave me a lot of answers when answering the question about the last weeks of life and various whereabouts of my relative through active research in the military archives helped. I can warmly recommend Mr. Haas. “

Dr. Markus Engelhard, Munich

  • „Extremely likeable, fast, reliable and highly competent – that has always been my impression of Benjamin Haas in our conversation. Having completed my own researches in the BA/MA in Freiburg for my books „Die Moltkes“ and „Verdun 1916“ Mr. Haas quickly finished smaller but nontheless ambitious researches for me. Apart from the archivists working in the BA-MA I do not know anyone as outstandingly versed concerning the tectonic of this archive as Mr. Haas. I can recommend his services without any restriction.“

Dr. Olaf Jessen, Historian

  • „Even though I love to come to Freiburg it is good to have Benjamin Haas at the place. He does his researches thoroughly and fast, has his results clearly arranged and his invoices are transparent. There is only one alternative to doing your researches on your own: Benjamin Haas.“

Florian Weiß, Curator of the Allied Museum Berlin

  • In connection with the writing of my novel about the Second World War it has been a great pleasure, professionally as well as personally, to work with Mr. Benjamin Haas. He immediately understood the nature of the project and the tasks he was given. He works in a precise, structured and thorough manner. His commitment and enthusiasm was very inspiring and he contributed to my novel with elements that I could not have thought of myself. I can clearly recommend him!

June Bach Pedersen, Private client and author

  • I’ve hired Benjamin on several occassion to help me investigate the files in the Bundesarchiv that relate to the disappearance of my uncle and his crew during WW2. He works quickly and helpful. He’s also very reasonably priced. I would definitely recommmend him if you need help accessing and finding any files in your search for information.

Nicola Gaughan, Private client

  • “In my research into the history of my family during the time of National Socialism and their possible involvement in its crimes, I would have failed in the military careers of my father and his two brothers without the help of Mr. Haas: The information from the Wehrmacht information center was for one Laypeople like me completely incomprehensible. Fortunately, I was advised to turn to him. Not only did he research all three careers and make them understandable for me and the family. Patiently and attentively, he also answered my many questions about how the three soldiers fit into the events at that time and about the individual scope of action of the three soldiers in their respective operational situations, and made this understandable for me with additional source texts and historical literature. It was a very pleasant collaboration, and I can only recommend him for “family researchers” like me. ”

Large projects with 5-10 cooperation partners under my leadership:

  • Schleswig-Holstein Ministry for Energy Transition, Agriculture and Rural Areas – Ordnance clearance in the North Sea see: https://www.schleswig-holstein.de/DE/Fachinhalte/M/meerespolitik/munition_meer.html  (…) “As part of an order from the special unit“ Munitions in the Sea ”of today’s Ministry for Energy Transition, Agriculture, Environment, Nature and Digitization of the State of Schleswig-Holstein, Mr. Benjamin Haas researched a whole range of data with his cooperation partners from the holdings of the Military Archives Department of the Federal Archives in Freiburg. The task at hand was to develop data on the pollution of the seas by fighting and munitions dumping. Mr. Haas and his team completed our order on time in autumn 2014 and delivered the expected result. Mr. Haas and his team worked carefully and to the fullest satisfaction of the client. “(…)
