Childhood in Breslau Ferdinand Lassal (he later adopted the French spelling "Lassalle") was born in
Breslau (now Wrocław),
Silesia,
Prussia, on 11 April 1825. His family were
Jews, originally domiciled in Poland, who had moved to Prussian Silesia in the late 18th century. His father, Heymann Lassal, who was trained for a
rabbinical career, was a prosperous wholesale silk merchant. Ferdinand had a sister, Frederike (Riekchen). For the New Year of 1840, his father gave him a diary. The boy, not yet fifteen, recorded his activities, faults, and good deeds, aiming to understand his own character. His early diary reveals a precocious, quick-witted boy, capable of warm affection but unscrupulous when he truly wanted something. He was a voracious reader with intense dreams of
knight-errantry and glory. He was highly sensitive about the figure he cut, his Jewishness, and his background as the son of a provincial tradesman. The diary shows an early interest in gambling, a keen eye for money, and a casuistic ability to justify his actions, such as playing billiards despite his father's prohibition. He also displayed a precocious interest in romantic intrigues, offering advice to family friends. The household was often tense due to quick tempers. Ferdinand formed a close alliance with his father, who was often disappointed by his wife's deafness and his daughter's perceived ignorance. However, Heymann himself was quick-tempered, and Ferdinand's dressiness and wilfulness led to friction. One serious quarrel over trousers led to Ferdinand contemplating suicide, an intention his father discerned and gently averted. Heymann generally treated his son as an equal, involving him in family discussions, particularly concerning Riekchen's marriage prospects. Lassalle was unhappy at school. He resented discipline and his reports were often unsatisfactory. To avoid his father's distress, he devised a method of forging his parents' signatures on the school report book. When this deception was nearly discovered, he decided he needed to leave Breslau and persuaded his father to send him to a commercial school in
Leipzig. His diary also reveals early idealistic convictions. He expressed a strong Jewish identity, dreaming of leading the Jews, "sword in hand, along the path to their independence", inspired by characters in
Edward Bulwer-Lytton's
Leila; or, The Siege of Granada.
Leipzig (1840–1841) In early May 1840, Ferdinand and his father travelled to Leipzig via
Berlin. Heymann arranged for Ferdinand to lodge with Herr Hander, headmaster of a , at a considerable expense that demonstrated his love for his son. Ferdinand, then fifteen, was treated as a young man of twenty in the Hander household. In Leipzig, Lassalle was often homesick and exasperated but rarely bored. His diary entries from this period reflect his developing revolutionary fervour, particularly in response to the
Damascus affair of 1840: "Cowardly race, you deserve no better fate! ... You were born to be slaves!" he wrote of the Jewish community's response. He read
Ludwig Börne's letters, seeing Germany as "one great prison where human rights are trodden under foot".
Heinrich Heine's poetry and
Friedrich Schiller's play
Fiesco also profoundly influenced him. After seeing
Fiesco, he reflected with "extraordinarily acute self-criticism": "Had I been born a prince or ruler I should have been an aristocrat, body and soul. But now, as I am only a poor
burgher's son, I shall be a democrat in good time". His reading of
Johann Wolfgang von Goethe's
Wilhelm Meister led him to contrast his own path with Meister's; while Meister renounced trade for Art, Lassalle felt he had renounced an "aesthetic life" for commerce to escape his "horrible position" at home. However, he firmly believed that fate, or Providence, would lead him to a life concerned with "Freedom rather than markets". His ambitions crystallized: "I will proclaim Freedom to the Peoples even if it costs me my life. I swear it by God and beneath the stars ... the blood of princes shall flow". Life with the Handers became strained as Herr Hander proved pompous and shifty. The death of the Handers' young daughter, Marie, to whom Ferdinand had grown attached, led to an uncomfortable interview where Hander revealed he had intended to ask Ferdinand to leave due to lack of space. School life also saw friction with the director, Schiebe. Ultimately, Lassalle decided against a commercial career. He persuaded his father, during a visit in the summer of 1841, to allow him to study at a university. He declared his intention to study history, "the greatest subject in the world", viewing it as a means to fight for humanity's highest ideals and to "enlighten and illumine" the peoples, rather than as a path to a traditional career.
University and Hegelianism Between leaving Leipzig and entering university, Lassalle lived at home in Breslau, studying for his matriculation. He developed an "iron determination to study", often remaining indoors for days, immersed in books. After initial refusal, his appeal to the Prussian Minister of Education allowed him to sit the matriculation examination in 1842. Though he impressed examiners with his essay on "The Development of the idea of the Humane", he failed due to the hostility of the presiding Commissioner, Dr. David Schulz. He passed the following year. Lassalle's university career was divided between the
University of Breslau (1843–1844 and summer 1845) and the
University of Berlin (1844–1845 and autumn 1845 onwards). It was in his early undergraduate days at Breslau that he discovered
Georg Wilhelm Friedrich Hegel. This was a "first big milestone" in his life, providing a creed that gave him "full satisfaction". He became a devoted Hegelian, though not an adherent of the
Young Hegelians. He described the philosophy as a "second birth" that gave him "clarity, self-assurance ... made of me self-containing Intellect, that is self-conscious God". Hegelian philosophy emancipated him from the revolutionary romanticism of Heine and made him a "determined socialist", albeit one who believed the new social order would arise from the "inevitable triumph of the Hegelian idea" rather than from barricades. His study of Hegel also reinforced his high regard for Prussia. Hegelian
dialectic became an instrument for solving problems in line with his own desires and contributed to his self-assurance, but at the cost of his sense of humour, proportion, and self-criticism. He joined the Raczeks, a Breslau student association dedicated to studying Hegel and his successors like
Ludwig Feuerbach and
Arnold Ruge. In April 1844, he moved to Berlin, living frugally at 52
Unter den Linden and dedicating himself to an austere regime of study, focusing on Hegel. He wrote a forty-page letter to his father outlining his Hegelian interpretation of history, industry, and the eventual emergence of a
Communist State where "man’s subjective individuality will come to real fruition in the conception of the State as an organised whole". His life in Berlin was not solely academic. He had a love affair with a musician, Lonni Grodzka, whom he helped marry off when he tired of her. He also formed a circle of followers, his "Triumviri": Arnold Mendelssohn (a doctor and cousin of the banking family), Alexander Oppenheim (a young lawyer), and Albert Lehfeldt (a student). Mendelssohn, in particular, fell under Lassalle's intellectual sway, writing letters of intense admiration. Lassalle's ambition at this time was to formulate his own philosophical system, with a work on
Heraclitus as a preliminary step to establish his academic reputation. ==Hatzfeldt affair (1846–1854)==
