In rough frontier cabins, tidy farmhouses, and elegant townhouses, Americans in the 1800s were dedicated to living as well and as comfortably as their circumstances allowed. The American home was a sacred institution, the seat of family life where the patriarch ruled with Mother at his side as guardian of the home, and the children were raised with strict discipline and strong values. Changes in taste and fashion, improvements in technology (indoor plumbing and a host of new laborsaving devices), and social change transformed home and family life in the 1800s, as opportunities for leisure activities and commercially produced consumer goods came within reach of the average American. But the strong American tradition of the sanctity of the home, consumerism, and the importance of a happy family life has its roots in the homes of nineteenth century Americans.
The farmers, workers, and pioneers of America in the 1800s were nourished by a tradition of hearty, down home cooking that is still a part of our national cuisine - New England baked beans, roast beef, turkey, corn on the cob, and pumpkin pies. With roots in the British Isles, and with important contributions from Native American food plants and cooking techniques, American food and drink quality and seasonal variety was vastly improved during the 1800s by new technologies in transportation, food storage, hygiene, and preservation, growing national and world markets, and not least the delicious ethnic cuisines of new immigrant groups. Hungry for innovation, quality, and economy, Americans in the 1800s became the best fed nation in the history of the world!
Medicine developed into a science in the 1800s, but it was a long evolution from folk remedies and superstition to a modern understanding of how the human body works and how disease is spread. Throughout much of the century, the life expectancy of the average American was decades shorter than it is now. A lack of understanding of simple hygiene contributed to the early death of many women after childbirth, and children routinely died of common childhood diseases like measles. An incorrectly treated broken arm could kill a healthy young man, and pain, disfigurement, and epidemic disease was the fate of many Americans. Traditional herbal remedies were sometimes the best treatments available, while patent medicines often contained toxic substances, and medical procedures were often painful, disgusting, and ultimately useless. The dedicated scientists and medical researchers of the 1800s made a tremendous contribution to the health and happiness of Americans.

Real-life crime dramas on television intrigue us with the details of postmortem examinations leading to the arrest of murder suspects, but how do forensic pathologists, the doctors who investigate unnatural deaths and chilling crime scenes, actually bring criminals to justice? The story lies in the body of evidence. Literally. The human body provides a wealth of scientific evidence that allows forensic pathology, or legal medicine, to help resolve criminal cases and convict even most elusive perpetrators. The human body records the story of a crime in the language of cuts, wounds, and bruises, and in the fingerprints and bloodstains. Forensic pathologists are trained to scrutinize and interpret this evidence in ways no other scientist can. Examining victims remains from the outside in, forensic pathologists investigate every inch of the human landscape to discover when, how, and why the victim died. Sometimes, a time of death is all a jury needs to convict a suspect of murder, and forensic pathologists are experts at uncovering this crucial evidence. Visiting crime scenes, collecting bodies in the middle of the night, and excavating suspicious burial grounds are all in a days work for the sake of bringing justice to victims who can no longer speak for themselves.
Who committed the crime? When? Even the smallest of witnesses can tell scientists stories that will make or break a criminal case. Insects and pollen grains help forensic scientists bring criminals to justice. A suspect escapes a crime scene, leaving not a trace of evidence behind - except for the hind leg of a grasshopper, which helps convict him of murder. A thief runs through a cornfield, relieved that no one saw him commit the crime - unaware of the tiny grains of pollen stuck to his shirt. Plants and insects hold clues to guilt or innocence. Evidence from nature is all around us, silently and swiftly leaving fingerprints, unnoticed by even the most cunning of criminals.
