Book excerpt: This book provides the most comprehensive history of German migration to North America for the period 1709 to 1920 than has been done before. Employing state-of-the-art methodological and statistical techniques, the book has two objectives. First he explores how the recruitment and shipping markets for immigrants were set up, determining what the voyage was like in terms of the health outcomes for the passengers, and identifying the characteristics of the immigrants in terms of family, age, and occupational compositions and educational attainments. Secondly he details how immigrant servitude worked, by identifying how important it was to passenger financing, how shippers profited from carrying immigrant servants, how the labor auction treated immigrant servants, and when and why this method of financing passage to America came to an end.
