About

Samantha Seligman-Grajewski

Founder. 3G. Engineering Remembrance.

Samantha Seligman-Grajewski works in process engineering and is completing her M.S. in Chemical Engineering at Stanford University. She is 3G, the granddaughter of Helen Landó Helman of Tiszabogdány, Subcarpathia, the sole survivor of her immediate family, and came to this work with no formal training in Holocaust or genealogical research.

In 2019 the family found a single prisoner card. Working from Kailua, Hawai‘i, she turned it into a dossier of more than 300 documents, developing a repeatable method for AI-assisted record linkage across a dozen multilingual archives. Among them are the Buchenwald intake photographs of Helen’s father and his two nephews, carters like him, taken one behind the other and numbered 322, 323 and 324, the first images her family had ever seen of anyone on Helen’s side. Through records alone she reconstructed the nephews’ survival path: both lived, and in 1945 they found Helen in Budapest and told her the family’s fate. The records converged with Helen’s own testimony, recorded more than twenty years earlier. Tracing their paths led her to a surviving branch of the family in Israel, lost for eighty years and now found.

Engineering Remembrance goes beyond her own family: she has given relatives documented records of family they had lost, and designed a framework so other descendants can recover their own, turning the bureaucracy built to erase these people into the instrument that returns their names.

A note on what this is not

This is not a commercial service and nothing here is for sale. It is one person’s research, written down so it can be reused. Conclusions are stated at the strength the evidence supports, and documents are cited on request.
