Input: Question: How many people live in the city where Herz was born? Passage 1:From 1916 to 1922, Thomson served on the Seattle city council, while continuing to work as a civil engineer. After leaving the council, he continued working various places in the Pacific Northwest and Alaska. He consulted on Oregon's Rogue River Valley Irrigation Canal; built hydroelectric plants in Eugene, Oregon and surveyed plant sites in Southeastern Alaska; planned the water supply of Bellingham, Washington and consulted on the system for Wenatchee; briefly, in his seventies, he returned, temporarily, as Seattle city engineer in 1930 to finish the Diablo Dam on the Skagit River after the death of city engineer William D. Barkhuff; consulted to the Inter-County River Improvement Commission for King and Pierce Counties (the counties containing Seattle and Tacoma, respectively), and consulted on the construction of the Lake Washington Floating Bridge (now Lacey V. Murrow Memorial Bridge, carrying Interstate 90 across Lake Washington) and for the foundations of the Tacoma Narrows Bridge.
 Passage 2:Born in Berlin to very poor parents, Herz was destined for a mercantile career, and in 1762 went to Königsberg, East Prussia. He soon gave up his position as clerk and attended the University of Königsberg, becoming a pupil of Immanuel Kant, but was obliged to discontinue his studies for want of means. He thereupon became secretary to the wealthy Russian Ephraim, traveling with him through the Baltic Provinces. On August 21, 1770, he traveled from Berlin and acted as respondent when Kant presented his Inaugural dissertation at the University of Königsberg for the post of ordinary professor. In 1770 he had returned to Germany and studied medicine in Halle, where he became an MD in 1774, in which year he established himself in Berlin, being appointed physician at the Jewish hospital. Beginning in 1777, he delivered public lectures on medicine and philosophy, which were well attended by the students and the principal personages of the Prussian capital. At some of them even members of the royal family were present.
 Passage 3:The Complete Compleat Enchanter is an omnibus collection of five fantasy stories by Ametican authors L. Sprague de Camp and Fletcher Pratt, gathering material previously published in three volumes as The Incomplete Enchanter (1941), The Castle of Iron (1950), and Wall of Serpents (1960), and represents an expansion of the earlier omnibus The Compleat Enchanter, which contained only the material in the first two volumes. The expanded version also differs from the previous omnibus by omitting its afterword, de Camp's essay "Fletcher and I". The omnibus is the first edition of the authors' Harold Shea series to be complete in one volume. It has appeared under three different titles. It was first published in the UK in paperback by Sphere Books in 1988 under the title The Intrepid Enchanter and with a foreword by Catherine Crook de Camp. The first US edition appeared under the title The Complete Compleat Enchanter, and replaces the foreword with a preface by David Drake. That edition was published by Baen Books in 1989, and has been reprinted a number of times since. Orion Books published an edition in the UK under the title The Compleat Enchanter in 2000 as volume 10 of their Fantasy Masterworks series. The stories in the collection were originally published in magazine form in the May 1940, August 1940 and April 1941 issues of Unknown, the June 1953 issue of Beyond Fantasy, and the October 1954 issue of Fantasy.
