Frederick Leypoldt

Frederick Leypoldt (born Jakob Friedrich Ferdinand Leupold; 17 November 1835 – 31 March 1884) was a German-American bibliographer, the founder of Library Journal, Publishers Weekly, Index Medicus and other publications.

Early life and education
Frederick Leypoldt was born in 1835 in Stuttgart, Kingdom of Württemberg, his name at birth being Jakob Friedrich Ferdinand Leupold. Leypoldt had an early liking for the drama and books, and he wrote a play as a youth, which he offered unsuccessfully to German managers. He left school in 1851.

Career
In 1854, he emigrated to the United States, where he simplified his name to Frederick Leypoldt. He entered the service of a bookseller in New York City, which, in 1859, helped him establish himself in business in Philadelphia. In Philadelphia, Leypoldt opened a bookstore and reading room, and in 1863 he began to publish first translations of foreign books, and later foreign textbooks with English notes. In January 1866, with Henry Holt, he established the publishing firm Leypoldt and Holt and moved to New York City. Under the anagram of "F. Pylodet", Leypoldt edited a successful series of French textbooks, wrote some German verse and translated some works into German.

Leypoldt and Holt continued, but in 1868 Leypoldt decided to devote himself personally to bibliographical work. The monthly Literary Bulletin, his first periodical, which he established in 1868, became the Trade Circular in 1870. In January 1872, the Trade Circular absorbed George W. Childs's Publishers' Circular and was published weekly.

In 1873, it became Publishers Weekly. Leypoldt published an American Catalogue for 1869, and in 1876 he began work on the American catalogue proper, which was completed in 1880. His Publishers' Uniform Trade-List Annual was begun in 1873, the Literary News in 1875, the Library Journal in 1876, and the Index Medicus, a monthly medical bibliography, in 1880. Most of these publications were continued by his friend Richard Rogers Bowker after Leypoldt's untimely death (Bowker having purchased Publishers Weekly from him in 1878). Leypoldt was among the founders of the American Book Trade Union in 1875,

Leypoldt was instrumental in establishing the American Library Association in 1876. He published the proceedings of the 1876 organizing conference in the first volume of Library Journal.

Frederick Leypoldt died in New York City on 31 March 1884. Writing of his death, Samuel Swett Green noted, "His friends believed that the zeal that was conspicuous in him led to strenuous labors in furthering his projects of the Publishers' Weekly, the Library Journal and the American Catalogue ...which shortened his life many years perhaps.". Leypoldt's widow, Augusta Garrigue Leypoldt, continued to work at Publishers' Weekly for thirty years.
