Bethel Henry Strousberg (20 November 1823 – 31 May 1884) was a German Jewish industrialist and railway entrepreneur during Germany's rapid industrial expansion in the 19th century.

He cemented his social standing with the construction of the Palais Strousberg in Berlin's Wilhelmstrasse, built in 1867–1868 according to plans designed by August Orth, which later became the seat of the British Embassy.

Baruch Hirsch Strausberg was born at Neidenburg (present-day Nidzica, Poland) in the Province of East Prussia, he changed his first names to Barthel Heinrich whilst attending the Gymnasium (Secondary School) in Königsberg.

He himself had to raise less capital while Strousberg's stockholders initially generated high profits, however, the nominal value of the shares reached dubious heights with regard to the actual costs of constructing.

Strousberg suffered a first setback after he reached a licence by the Hohenzollern prince Karl Eitel Friedrich, ruler of the Romanian United Principalities as Carol I since 1866, for another railway project bypassing the navigation on the Danube river largely controlled by Austria.

His political opponents, led by the National Liberal Eduard Lasker, openly denounced his financing methods and his ties with the state government, enforcing the Prussian trade minister Count Itzenplitz to resign in 1873.

He was deported and returned to Berlin, dividing his time between London and the manor of his son-in-law in Bromberg, whilst attempting his social rehabilitation with various projects and writing his memoirs.
