The Jackknife Bridge, Chicago, Illinois. (1907)

The Jackknife bridge, designed by William Scherzer and built in 1895, spanned the South Branch of the Chicago River between Jackson and Van Buren Streets. It had two side-by-side double railroad tracks used by Chicago elevated 'L' trains until the late 1950s.

The two halves resembled a pair of gigantic steel face-to-face rocking chairs, which rocked back and away from each other when opening. The bridge no longer exists.

Citation-Free Writing as a Pedagogical Tool

Citation-Free Writing as a Teaching Tool. The lack of inline citations in this journal is intentional. It follows a long tradition in respected popular history and journalism—such as Smithsonian Magazine and American Heritage—where writing is meant for a broad, curious audience rather than only academic specialists. Instead of supplying ready-made source lists, these articles are meant to spark independent research. Students and researchers are encouraged to investigate claims, check facts, and build context independently. This active approach promotes a sense of intellectual ownership, strengthens research skills, and deepens understanding of history. A Lifelong Commitment to Historical Inquiry Dr. Neil Gale has devoted decades to the study and teaching of history. From his first work at the 1979 Chicago Metro History Fair to his continuing mentorship through Illinois History Day, his focus has always been on context, complexity, and curiosity—not just on collecting facts. His work models history as an ongoing conversation rather than a fixed record. Educators across Illinois and beyond have embraced this approach because it helps students build strong research habits and confidence in working with complex historical material. These articles serve as starting points, encouraging future historians to ask questions, follow evidence, and develop interpretations in their own voice. A Dynamic, Multidisciplinary Method. This journal treats history as more than a simple timeline of events. It combines: ● Narrative construction – shaping events into meaningful stories. ● Comparative analysis – examining different communities and civilizations across time and place. ● Cultural mapping – exploring how memory, identity, and place interact. By blending careful archival research with thoughtful storytelling, this method helps historians and students: ● Place events within broader social, political, and technological contexts . ● Compare societies across time and geography to see patterns and differences. ● Create narratives that respect both emotional truth and factual evidence, turning archival records into lasting historical insight. ● Review and Evaluation Entries in this journal are periodically reviewed for clarity, accuracy, and educational value. Readers, educators, and subject-matter experts are invited to offer comments and corrections. This open, collaborative process reflects the journal’s core belief that history is a shared endeavor, strengthened by many voices. How This Journal Uses Sources ● This journal does not use inline citations on purpose. That choice is part of how it teaches history. ● It follows the tradition of trusted history magazines like Smithsonian and American Heritage. Those publications are written for curious readers, not just college professors. In the same way, this journal is meant to be readable, engaging, and open to a wide audience. ● Instead of giving you every source up front, the articles are meant to be starting points. You are invited to: Track down where a claim might come from. Check facts by looking at other books, documents, or websites. Build your own understanding of the time period or event. Working this way helps you: ● Take ownership of your research. ● Build stronger research skills. ● Develop a deeper understanding of history because you discover things for yourself. ● These articles are invitations, not final answers. ● They encourage you to ask questions, follow clues, and explain the past in your own voice. Dr. Neil Gale’s Work in History Dr. Neil Gale has spent many years studying and sharing Illinois history. He began this work in 1979 at the first Chicago Metro History Fair and has continued mentoring students through Illinois History Day. His goal is not just to list facts. He wants readers and students to: ● See how events fit into a bigger story. ● Understand that history is complex, not simple. ● Stay curious and keep asking “why” and “how.” Dr. Gale’s approach shows that history is not a frozen list of dates. It is more like an ongoing conversation across time. Many teachers in Illinois and beyond use this journal because it: ● Builds research and critical thinking skills. ● Helps students feel more confident reading and using historical sources. How This Journal Teaches History. This journal treats history as more than a timeline. It combines: ● Storytelling – turning facts into clear, meaningful stories. ● Comparing and contrasting – looking at different communities or time periods side by side. ● Cultural mapping – asking how people’s beliefs, memories, and identities shape events. ● Using both careful research and strong storytelling, this method helps students and historians: ● Put events in a larger social, political, and technological context. ● Compare different places and times to see patterns and differences. ● Write stories that are both accurate and emotionally honest, turning old records into powerful histories. How Articles Are Reviewed Entries in this journal are checked from time to time for: ● Clarity – Is the writing easy to understand? ● Accuracy – Are the facts correct? ● Educational value – Will this help students and teachers learn and teach history? ● Readers, teachers, and experts are welcome to send in comments or corrections. This open style of review aligns with the journal’s central idea: that history is something we explore together, not alone. ..............................................
