Alternate spellings: Isaac, Isaak, Jssak.

Childhood

Isak Mamo Abraham was born on September 16, 1883, in Rustschuk, Bulgaria. He was the third son of Mamo Abraham and Lea Jacob.

By the time he was ten years old, both his parents had died of tuberculosis. He was then raised by his maternal grandparents, Salomon (Moni) and Rebecca Jakob.

Nothing else is known about his early life.

Adult life

Unlike his brothers Haim, Moritz and Moni, Isak apparently never moved to Constantinople. Instead he spent his early adult years in Varna, Bulgaria.

Varna was a large port on the Black Sea, the third largest city in Bulgaria and the second most important business center.

One of the very few surviving documents related to Isak is his business card:

Isak Abraham
"Ex Fondé de Pouvoirs de la Societe de Crédit Ghirdap"
Varna

Crédit Ghirdap was the first Bulgarian Bank which had been founded in 1881, with branches in Roustchouk, Sofia and Varna. The title "Fondé de Pouvoirs" can be translated as "Authorized Representative", or "Authorized Officer".

Isak's name appears (Russified as Isaac Avramoff) in the publication "Zionist Work in Palestine" (1911) (London : Pub. on behalf of the Zionist Central Office by T. F. Unwin). His name is listed as the representative of the Jewish National Fund Agency in Bulgaria:

"The following Collecting Agencies (of the Jewish National Fund ) will supply any further Information and receive Contributions"

"Bulgaria: Isaac Avramoff, Directeur de la Societe de Credit "Ghirdap", Varna"

Isaac Avramoff, Directeur de la Societe de Credit Ghirdap, Varna

Isak's name also appears in three issues of "Die Welt", the publication of the Zionist Organisation, listing donations he collected. (10 February 1911, #6, 7 April 1911, #14, July 19 1912, #29).

If, as I assume, "Isak Abraham, Ex Fondé de Pouvoirs de la Societe de Crédit Ghirdap" and "Isaac Avramoff, Directeur de la Societe de Credit Ghirdap, Varna" are one and the same person, these listings provide some interesting information.

First, they indicate that Isak was succesful at a relatively young age - he would have been the head of a branch of a bank when only 28.

They also show that, like his brothers Haim and Moritz, he was involved in Zionist activities - apparently in charge of fund raising for Bulgaria.

Berlin

In 1924, Isak sent a photo from Vienna to his brother - whom he called "Moise" - with wishes for the Jewish New Year. It is not known if he resided in Vienna or was just travelling.

In January 1931, Isak sent a photo to his brother, whom he now called "Moritz". Isak by now resided in Germany, Berlin-Friedenau, Kaiser allee 66.

Isak Abraham never married and left no descendants. He died on December 11, 1931, at the age of 48. His occupation was listed as "Kaufmann" (businessman/trader/merchant). His last home was Berlin-Friedenau, Kaiser allee 66 (although in a document dated 1956, his last address was given as Berlin, Wittenbergerplatz, "in a well-known pension".)

Isaak was buried in the Weissensee Jewish Cemetery in Berlin.

Isaak's Will

The beneficiaries of Isaak's will were two of his brothers - Chaim (Haim) and Moni - and his two nephews - Gideon (Gisy) and Uriel. Missing from the will was his third brother Moritz. It's not known whether this was because of a falling out between Isaak and Moritz.

At the time of his death, Isaak owned or co-owned seven rental properties in Berlin. It's not clear what happened to his estate, however what happened to one of the properties would trigger a lengthy lawsuit initiated by Ronya after the war.

According to documents related to the case, the property was supposedly bought in 1934 by person also named Isaak Abraham. After his death in 1938, the property was then sold for a fraction of its value due to the Aryanisation laws. According to Ronya, it was difficult to believe in such a coincidence, and she argued that it had to be a hoax as Jews couldn't buy real estate in 1934 but were instead pressured to sell what they owned. Despite years of proceedings, the lawsuit ended unsuccessfully in 1957.
