Work in the Lódz Ghetto

The Lódz Ghetto was created in February 1940 and sealed off from the rest of the world from May 1940 until its liquidation at the end of August 1944.  Initially inhabitants survived by selling whatever they could in exchange for food, clothing, and other necessities.  At the outset, some inhabitants received packages from relatives and friends on the outside, but these were often pilfered and eventually stopped arriving altogether.  For a while the appointed chairman of the ghetto, Mordechai Chaim Rumkowski, succeeded in making the ghetto indispensable to the Nazi war machinery by establishing a huge work force that would serve the German war effort and thus ensure the residents' survival.

Work became the gold currency.  Without a labor force, the sealed community could not obtain money for food and other necessities.  Without work, one did not get the meager bowl of soup distributed at the factories.  Without work, one could be deported.  They had not yet learned that deportations would take place with or without those work assignments.  Work was compulsory for everyone between the ages of 10-65 years of age.  Having a Work ID Card and an employment salary book would, they reasoned, keep them alive for another day. 

There were 18 workshops in 1940.  By 1943, that number increased to 93 enterprises (ressorts), where 70,000 people, 85% of the ghetto population, were employed in these businesses.  In his diary in August 1941, Dawid Sierakowiak writes: "A large number of new workshops and factories are being established.  Together with those already existing, they form what's called in jest the 'Jewish Industrial District'." As the numbers increased, many of the indoor enterprises had several locations, and most of the long working hours took place in small, overcrowded, unsanitary conditions.  (See List of Labor Departments in the Lódz Ghetto below.)

All the workers, children and the elderly alike, needed Work Identification Cards (ID Cards).  These cards were reportedly distributed at the work places by the managers.  Workers were warned that without that card, one would be considered unemployed.  It had to be kept in a protective folder, and any alterations made to the card meant punishment to the holder.

The Project - Origin of the Data

The Work Identification Cards were reportedly distributed by the managers of the enterprises and required to be carefully held by the workers in the Lódz Ghetto.  Some survivors think that the administration at the Employment Office kept the application forms for the Work ID Cards, which look very similar to the actual cards. 

This type of Work Identification Card was distributed after January 1, 1943.  This database does not contain ALL the names of the working population in the Lódz Ghetto.  Other forms of Work Identification Cards were in use before this date and could still have been used concurrently. 

Survivors present in Lódz immediately after the war have provided testimony that many of the cards were missing.  One survivor reported that she obtained her card surreptitiously immediately after the war.  From comparing existing work cards in this collection to work cards that should have existed per the recollections of survivors or family, it appears that some of the cards may have been removed before the collection was copied.  Therefore, we can not assume that this collection includes 100% of all work cards that were issued.  Based on this information, some of the cards researchers are seeking may not be available.

Our collection is comprised of 23 reels of microfilm housed at the United States Holocaust Memorial Museum (USHMM).  This database will serve as a finding aide for the Museum.  Given the ID number and/or worker name, a researcher will be able to request a copy of an ID Card.  Since the ID numbers were often hard to read, it is strongly recommended to supply the person's full name when requesting a copy of a card.  (Please see Acknowledgement section for the US Holocaust Memorial Museum's email address.)

Format of Work ID Cards

There are between 800 and 1600 frames on each of the 23 reels of microfilms.  The cards have two sides that contain some or all of the following information:

This database includes over 13,200 records.

In compiling the online database, information was organized for clarity based upon the order presented on the Work ID Card.  Not all cards contain all the following information.  Many cards were very hard to read.   The fields of the database are as follows:

  • Reel Number
  • Image number
  • Worker Number
  • Surname
  • Given Name
  • Date of Birth
  • Address in the ghetto (See Reference Link #2 below)
  • Place assigned to work (See List of Labor Departments in the Lódz Ghetto below)
  • Type of employment (See Reference Link #4 below)
  • Starting date of employment
  • Photo included on card: Yes/No
  • Signature of worker on card: Yes/No
  • Starting date of employment (date of Lódz Ghetto Work ID Card)
  • Learned Trade
  • Acquired skill
  • Gender
  • Age in years as of January 1, 1943 (See Note #3 below)
  • Worked since
  • Unemployed from….to…[or other places of employment] (See Note #6 below)
  • Comments (includes transport and death dates if applicable)
  1. Data entry volunteers indexed all legible entries and as much as possible from the illegible entries, sometimes providing parts of words and number series which may help researchers identify people of interest. 

  2. The Lódz-Ghetto card dates were entered in the Ghetto by different people.  Some used German, others Polish.  Therefore the months were variously in German abbreviations, Polish abbreviations, Roman numerals, or Arabic numbers. 

  3. The age of the worker given is as of January 1, 1943.  However, workers were frequently listed as one year older, since the clerks in Lódz apparently subtracted the year of birth from 1943, and therefore listed the age of the worker's next birthday. 

  4. In order to survive, ghetto inhabitants frequently lied about their ages to avoid deportation and/or to qualify for work.   In September1942, children less than 10 years old and adults over 65 were deported to the death camp in Chelmno. 

  5. Volunteer Fritz Neubauer reported that there is an official list of businesses in the Lódz Ghetto, called "Verzeichnis dis bis Betriebe in Litzmannstadt-Getto," from January 1943.  This may be available in some Holocaust libraries and/or museums. 

  6. The "Unemployed from… to…" phrase is on the backs of the cards.  However, it seems that instead of unemployment dates, additional work experiences were listed here.  Data entry volunteers had no way of determining which, if any, were actually dates of unemployment.  The listing seems to be places and dates of other employment. 

  7. A few transport dates listed were obtained from other JewishGen Holocaust databases and listed in brackets to indicate they are from other sources.  Since these transports must have occurred later, the Worker Identification Card does not include a TRANSPORT stamp. 

  8. Any other data in brackets indicates that the information was taken from another source, not the Work ID Card.  Researchers need to corroborate all dates and ages, since they vary greatly for the same person on the various source documents. 

  9. Although the Gestorben stamp does say "auf Grundn von" (cause of death), in reality the handwritten information does not provide the cause of death.  It states the name of the institution, mostly the business name, from where the information about the worker's death was provided, i.e. where the deceased person worked. 
Searching Strategies

The spelling of surnames was not consistent.  Always check all possible spelling variations when doing a database search.

Do not enter accented characters in the search fields.  If you do, you will NOT get the results you are expecting.

There are two Polish accented characters, the Ogonek E (Ę) and the Ogonek A (Ą) which sufficiently modify the pronounciation of a surname or town name to also change the soundex code.  The addition of the ogonek (little hook) beneath it causes the vowel to be pronounced with an additional "n" or "m".  For instance the town name Częstochowa is pronounced Czenstochowa or the surname JASTRZĘBSKA is pronounced JASTREMBSKA.  To get the search results you want, use the “sounds like” search and add the N or M to the name after the vowel.  Do not use an exact name search.

The creation of this database could not have happened now if it were not for the generosity of Richard J. Astor. He was interested in finding a significant way in which to honor the memory of his father, Alec Astor Z"L, born Ajzyk Abersztajn in Lódz in 1915, who survived the Holocaust and died in London in 2006. We are very grateful to Richard Astor for funding this entire project.


The information contained in this database was indexed from the files of the United States Holocaust Memorial Museum (USHMM File RG 15.083M, Reels 693 - 696).  JewishGen volunteers, Nolan Altman and Roni Seibel Liebowitz, coordinated the data entry and proofreading processes, respectively.  We also wish to thank Fritz Neubauer for creating the Lódz Establishment list, and for sharing his personal knowledge about these Work ID Cards, explaining that this collection contains only those newly-issued work passes after January 1, 1943.  He also was a great help in deciphering many only partially legible German entries.

The following data entry volunteers worked on this project: Olivia Berkowicz, Bettie Black, Sharon Brearey, Fay Bussgang, Kurt Friedlaender, Marianna Hoszowska, Avraham Kano, Sandy Malek, Joan Maplesden, Edward Mitelsbach, Fritz Neubauer, Peter Reiniger, Diana Seldes, Marilyn Shalks, Limor Shenhar, Jolie Weininger, Irit Weisel, Naidia Woolf, and Paula Zeiselman.

The volunteers who proofread the entries are: Helene Celnick, Gene Dershewitz, Anna Dunn, Helene Lajzerowicz, Orit Lavi, Dorothy Leivers, Roni Seibel Liebowitz, Fritz Neubauer, Fay Nissen, Sandra Paikin, Debby Painter, Zipi Pittel, Rosa Raskin, Barbara Ringel, Deborah Rosenberg, Merav Schejtman, Ruth Shaw, Nancy Siegel, Jackye Sullins, Eric Svirskis, Sandra Walker, Joanna Winter, and Naidia Woolf.

The task of proofreading each and every entry is laborious, requiring volunteers to check every entry in each column and compare them to what is written on the cards, which are often illegible.  Then uniformity in formatting of information is reviewed.  A number of the reels were rescanned when due to missing entries.  I am very grateful to assistant Naidia Woolf who checked most of the rescanned reels, added the missing entries, and did all the required re-numbering on these files.  Lastly, the files were sent to Fritz Neubauer for a final look at uncertain entries and a full review of the German spellings and grammar. His help has been invaluable.

In addition, thanks to JewishGen Inc.  for providing the website and database expertise to make this database accessible.  Special thanks to Susan King, Warren Blatt and Michael Tobias for their continued contributions to Jewish genealogy.  Particular thanks to to Nolan Altman, coordinator of Holocaust files.
