The history of the Lazard family belongs to that singular phenomenon of nineteenth-century Europe: the migration of Jewish Lorraine brotherhoods to the New World, where retail trade transformed, within a single generation, into international finance. Hailing from a borderland region — Lorraine and its Saar marches, a land of ancient rural Judaism —, the Lazard brothers embody the trajectory of a diaspora at once rooted in its villages of origin and capable of crossing the Atlantic, then the American continent, at the pace of steamships and telegrams. The history of Lazard begins in the era of steamships and telegrams, with the emigration of five French brothers and several cousins to the United States.
This Great Book sets out to trace this lineage not as a mere corporate chronicle, but as a family and diasporic History: from the Lorraine market towns of Sarreguemines and Frauenberg to the trading floors of today, by way of antebellum New Orleans, the California Gold Rush, Paris under the Second Empire, and New York at the height of triumphant capitalism. Where the archives speak — articles of association, census records, notarial registers — we shall establish the facts; where only tradition transmits, we shall say so. Such is the rule of this work: to distinguish the established from the probable, Memory from History.
The origins of the Lazard family are rooted in the rural Judaism of Lorraine and the Sarre, a landscape of villages where Jewish communities, long subject to restrictions, lived from peddling, cattle trading, and small textile commerce. Reference sources place the family's cradle in this border region. Alexandre Lazard was born in the early nineteenth century in Sarreguemines, in Lorraine, France, and emigrated to the United States in 1847.
The firm's own historical record specifies more precisely the origin of the senior branch. In 1841, Alexandre and Lazare Lazard, two brothers from Frauenberg, in France, arrived in New Orleans. Sarreguemines and Frauenberg, a few kilometers apart in the Moselle country, both belong to this same Lorraine world: the joint mention of the two place names in the sources reflects the internal mobility of a family whose Memory and archive correspond without always coinciding perfectly. This nuance — a cradle identified at times by the town, at times by the neighboring village — illustrates the ordinary difficulty of diasporic genealogy, where the place of birth, the place of residence, and the place declared to American authorities do not necessarily overlap.
What emerges with certainty is the collective character of the migratory enterprise. This was not an isolated individual but an extended brotherhood of siblings, accompanied by cousins, transplanting an entire network of solidarities across the Atlantic. It is precisely this clannish structure — in which blood ties formed the foundation of business ties — that would constitute, for decades, the strength of the house of Lazard.
The year 1848 marks the formal founding of the house. The young brothers, freshly arrived, open a trade in fabrics and various goods. On July 12, 1848, three French brothers, Alexandre Lazard, Lazare Lazard, and Simon Lazard, founded Lazard Frères & Co. as a dry goods store in New Orleans, Louisiana.
The date of July 12, 1848 stands as the founding act, and biographers have consecrated it as such. Simon and his brothers signed a partnership agreement for "Lazard Frères" on July 12, 1848, the birth certificate of today's multinational Lazard. The contract associated very young men whose commercial practice was shaped by the economy of the American frontier. They immediately set about buying goods wholesale in the city and traveling through the countryside to sell them retail to settlers and farmers.
Some sources offer a slightly different composition of the brotherhood associated with the origins, incorporating the brother Élie alongside Simon. Alexandre Lazard settled in New Orleans where he launched a dry goods business and, in 1848, took his two brothers Simon and Élie on as partners. These variations between reference catalogues — regarding the exact identity of the initial partners and the order of their entry — reflect the fluidity of a family firm in which brothers entered and exited the capital according to their successive settlements. The essential remains established: a retail trading house, founded by brothers from Lorraine, in the cotton South before the Civil War.
The fate of the house pivots with the discovery of gold in California. The siblings, following their logic of expansion through dispersal, redeployed their forces toward the Pacific coast at the turn of the 1850s. By 1851, Simon and two other brothers, Maurice and Élie, had all settled in San Francisco, California, while Alexandre remained in trade.
San Francisco became the stage of the decisive metamorphosis: from cloth to credit, from the dry-goods counter to the bank. As early as 1851, Lazard Frères had established itself in San Francisco, where it would develop into banking and exchange. In a city where gold-seekers and capital converged, where gold itself had to be weighed, discounted, shipped, and converted, currency exchange and financing quickly proved more lucrative than selling goods. The family thus took the step that distinguishes the merchant from the banker: transforming the circulation of goods into the circulation of money itself.
Simon Lazard embodies this transition better than anyone. Simon Lazard (April 8, 1828 – February 24, 1898) was a Franco-American banker who co-founded Lazard Frères & Co. His biography alone traces the complete arc of the lineage. A native of Lorraine, a young merchant in antebellum New Orleans, a pioneer of the California Gold Rush, and, ultimately, an international banker. In a single lifetime one can read the passage from rural Europe to global high finance — the very essence of the family's adventure.
The structural strength of Lazard lies in its triangular configuration: three houses, three financial capitals, one name. Buoyed by Californian prosperity, the brothers redirected their activity toward banking proper and wove a network linking the United States to France. The return toward Europe opened the Parisian chapter, natural for a family that had remained French in language and attachments, and completed the New York apparatus on the Atlantic coast.
This three-pole architecture — La Nouvelle-Orléans and San Francisco first, then Paris and New York — made Lazard a rare thing: a truly transnational investment bank ahead of its time, capable of arbitrating between financial centers, financing international trade, and advising governments and enterprises on both sides of the ocean. The cohesion of the whole rested on the entry of cousins and allies into the partnership, perpetuating the clannish model of its origins: the house remained, by principle, a family affair built on trust.
At the turn of the twentieth century, the house had established itself as one of the great names in international finance. LAZARD, family of international bankers: the formula of encyclopedic dictionaries consecrates the completed transformation. From Lorraine textile merchants, the Lazard had become a financial dynasty whose influence radiated across the three principal centers of the Atlantic world.
The period separating the two world wars saw the house reach the apex of its prestige and consolidate its grip on the banking world. This is the age when the firm ceased to be a fraternal affair and became an institution led by men of the first rank, yet perpetuating the family logic through alliances. The interwar period saw Lazard secure a supremacy in the banking world.
As the founding generation disappeared — Simon Lazard died in 1898 — leadership passed to new figures, drawn from the allied branches of the family, who stamped upon the house its character as an elite investment bank. This continuity through kinship, rather than through blood brothers alone, ensured the perpetuation of a name that had become a brand. The firm preserved its tripartite identity while adapting to the monetary upheavals, crises, and reconstructions that punctuated the first half of the twentieth century.
This era also consecrated an enduring trait of the house's culture: the primacy of financial counsel and the execution of transactions on behalf of clients, rather than the accumulation of proprietary capital. Lazard devoted itself to its fundamental enterprise: financial counsel and the execution of transactions on behalf of its clients. This doctrine of "human capital" over the balance sheet would become the firm's signature and would account for its singular longevity among investment banks.
For a century and a half, Lazard remained what it had been at its founding: a private partnership, in which the partners pledged their name and their fortune. A private partnership — incorporated in 1848 under the name Lazard Frères. This structure, inherited directly from the agreement signed by the brothers in 1848, perpetuated in modern legal forms the clannish spirit of the Lorraine origins.
The turn of the millennium marks the end of this century-old model and the house's entry into the era of listed capitalism. Lazard Frères & Co. was reorganized in 2000 under the name Lazard. This reorganization, followed by a public offering, transformed a venerable partnership into a public entity while preserving its original trade. The firm provides advice on mergers and acquisitions, partnerships, institutions, governments and private clients.
Today, the name Lazard designates a global financial institution that claims direct lineage from the 1848 act. The partnership "Lazard Frères" signed on July 12, 1848 constitutes the birth certificate of the multinational Lazard of today. Thus, from the dry-goods store in La Nouvelle-Orléans to the contemporary listed company, runs an unbroken line of transmission — a remarkable fact for a house whose origins trace back to a fraternity of Lorraine peddlers.
The history of the Lazard family offers one of the best-documented examples of a dynamic particular to the Jewish diaspora of Western Europe in the 19th century: the transition from rural trade to high finance, carried out by a united fraternity and reproduced from generation to generation through the play of family alliances. Setting out from the villages of the Saarish Lorraine, the Lazard brothers founded in 1848 a house that was to outlive its founders, survive two world wars, and rise to the rank of a global investment bank.
What strikes one in this trajectory is the continuity of the name and of the vocation. From the dry-goods counter to mergers-and-acquisitions advisory, the house never disavowed its original calling: to make value circulate, to intermediate trust. The triangular structure — La Nouvelle-Orléans, San Francisco, then Paris and New York — and the model of the family partnership ensured a longevity that few financial institutions can claim. Where family Memory and the archive converge is in the sacred date of July 12, 1848, a golden thread linking the Lorraine village to global finance. The Great Book Lazard is thus that of a diaspora which knew how to make mobility a strength, and the bond of blood an institution.
