American Society of Civil Engineers
Excerpt: 

For the Millennium Challenge, ASCE canvassed its members in late 1999 to determine the 10 civil engineering achievements that had the greatest positive impact on life in the 20th century. Rather than individual projects, they chose to recognize broad categories of achievements.

ASCE's members ranked the 10 greatest civil engineering achievements as:

Airport Design And Development
Dams
The Interstate Highway System
Long-Span Bridges
Rail Transportation
Sanitary Landfills/Solid Waste Disposal
Skyscrapers
Wastewater Treatment
Water Supply and Distribution
Water Transportation

Annotation: 

The American Society of Civil Engineers polled its membership to rank the ten civil engineering achievements that had the “greatest positive impact on life in the 20th century.” Those achievements are featured in the Monuments of the Millennium exhibit, and include Airport Design And Development, Dams, The Interstate Highway System, Long-Span Bridges, Rail Transportation, Sanitary Landfills/Solid Waste Disposal, Skyscrapers, Wastewater Treatment, Water Supply and Distribution, and Water Transportation. There is an introduction for each section, accompanied by a highlighted national or international project with images and links for more information. The site is small, but has a good overview the types of projects ASCHO members believe to be the most significant public works of the past century.

Excerpt: 

Welcome to the Invisible Revolution, the story of Doug Engelbart, the man who invented much of the computer environment we live in today - and still few know his name. This is his story, and the story of his fellow dreamers, thinkers, doers - revolutionaries - who changed our lives forever.

Annotation: 

This site represents a documentary film project produced by Frode Hegland, Fleur Klijnsma and others. The vision for the documentary is to present the story of how Doug Engelbart invented the mouse and began a revolution in information processing by popularizing the graphical and interactive, nonlinear
format that dominates computer technology today. The materials here include "a casual, rough and ready series of interviews, links to his seminal papers, and a cheat-sheet-like timeline." Although the site is essentially a companion to a film, the sections on Engelbart's life, vision, papers, and timeline can be very useful to historians. The site also has a list of the interviewees who contributed to the documentary's story with short bios that could link important personalities and establish new leads for researchers. The film clips might also be helpful or interesting to historians who want to explore documentary film or other visual modes of recording and conveying history.

Excerpt: 

The history of engineering can be roughly divided into four overlapping phases, each marked by a revolution:

Pre-scientific revolution: The prehistory of modern engineering features ancient master builders and Renaissance engineers such as Leonardo da Vinci.

Industrial revolution: From the eighteenth through early nineteenth century, civil and mechanical engineers changed from practical artists to scientific professionals.

Second industrial revolution: In the century before World War II, chemical, electrical, and other science-based engineering branches developed electricity, telecommunications, cars, airplanes, and mass production.

Information revolution: As engineering science matured after the war, microelectronics, computers, and telecommunications jointly produced information technology.

Excerpt: 

Before we continue describing the evolution of ways to mark the passage of time, perhaps we should broadly define what constitutes a clock. All clocks must have two basic components:

a regular, constant or repetitive process or action to mark off equal increments of time. Early examples of such processes included the movement of the sun across the sky, candles marked in increments, oil lamps with marked reservoirs, sand glasses (hourglasses), and in the Orient, knotted cords and small stone or metal mazes filled with incense that would burn at a certain pace. Modern clocks use a balance wheel, pendulum, vibrating crystal, or electromagnetic waves associated with the internal workings of atoms as their regulators.

a means of keeping track of the increments of time and displaying the result. Our ways of keeping track of the passage of time include the position of clock hands and digital time displays.

The history of timekeeping is the story of the search for ever more consistent actions or processes to regulate the rate of a clock.

Excerpt: 

Welcome to my website, the Bell System Memorial. For those of us who were old enough to remember the days of "Ma Bell" you should find plenty of memories on this website of the "good old days" - and perhaps some not-so-good old days - under the Bell System monopoly.

Review: 

A Switchboard to the History of the Telephone: The Bell System Memorial Website

In the golden days of the Bell telephone monopoly, telephones did not beep, chirp or yodel. Telephones made only one sound: they rang. In those golden days, there was no confusing variety of telephone providers, vying with each other to offer better long distance deals. There was one provider for local and long-distance calls, and this was Bell.

Ma Bell, the company of companies, was much more than a telephone provider: it was a symbol of American enterprise, of innovation and progress. Bell was not a company in the strict sense, but was an aggregate term for AT&T encompassing 24 Bell operating companies that provided local phone services. Under the umbrella was also the AT&T long distance service, an equipment manufacturing arm known as Western Electric, and the research and development division "Bell Laboratories." At the time of its break-up after de-regulation in 1984, Bell was the largest employer in the United States. Bell had not only provided a telephone for the majority of American households, but also a regular income for over a million workers.

The Bell System Memorial website is dedicated to an era of the telephone that was lost with de-regulation. It is a memorial to the technology of the telephone, and a memorial to the workers who made the phones ring. The website is a labor of love by David Massey, a private telephone enthusiast who was not associated with any of the former Bell companies.

The design of the website is clear and intelligent, resembling the functionality of a telephone switchboard: The main index site provides four options for different groups to enter the site: for students and teachers, for former employees, for historians and researchers, and for hobbyists and collectors. By providing these different entrance points, David Massey manages to address a wide audience, and at the same time tailors more specific information to a variety of groups.

When entering through the former employee button, visitors can access a fascinating collection of stories by former AT&T, Western Electric, Bell Labs, and Bell Operating Company employees. In this section, former employees recall "the wonders of working at Ma-Bell." They write about the stages of their careers at Bell, their most extraordinary work experiences, and the comradery among Bell employees. Not all stories reflect a harmonious relationship between the employer and the employees: Peter W. Koch, a former Western Electric installer, tells of a long strike in 1952 to raise the per diem rate for traveling installers by one dollar. In 1958, due to a recession, "about a third of the installers were laid off." Among them was Peter W. Koch, who "was never recalled." This section also gives a sense of the skills that were lost in the course of technological progress. Mary Clemence, who worked as a switchboard operator in Michigan in the mid 1960s, recalls her skills in handling a switchboard from the 1920s. "I've realized for some time that I had an incredibly unique experience using that kind of equipment, at a time when most of the country had direct dialing for local and long distance calls."

In addition to these stories, visitors can access a wealth of material through a navigation bar on the left hand side: a short history of the Bell logo, recordings of Jane Barbe's voice, Yellow Pages for telephone collectors and much more. A search engine helps to find pathways through Bell's A-Z. A What's New page keeps regular visitors up-to-date about additions to the site.

For historians of technology, for students and teachers, for anyone who has phone-nostalgia and wants to have a good time, the Bell System Memorial is the place to go. This website rings.

Excerpt: 

Am I pregnant? The answer to this age-old question once demanded a combination of guesswork, intuition, and time. In 1978, however, the long wait to know for sure became a thing of the past. Trumpeted by advertisements as “a private little revolution,” the first home pregnancy tests started appearing on drug store shelves that year. A quarter of a century later, innovations promise to make even the telltale thin blue line obsolete. This web site looks at the history of the home pregnancy test—one of the most ubiquitous home healthcare products in America—and examines its place in our culture.

The home pregnancy test works by identifying the presence of the “pregnancy hormone,” human chorionic gonadotropin (hCG), in urine. Research that led to a sensitive, accurate test for hCG was done by scientists in the Reproductive Research Branch of the National Institute of Child Health and Human Development at NIH.

Annotation: 

A Thin Blue Line: The History of the Pregnancy Test Kit, an online exhibit at the National Institutes of Health, explores the history of the pregnancy test kit from the laboratory to the digital age and invites women to share their personal stories through an online survey. In addition to the scientific background on the research that led to the development of the test, it also includes an historical timeline of pregnancy testing, as well as early advertisements for the test and portrayals of the test in television. There are excerpts from oral histories and interviews with Judith Vaitukaitis, M.D. and Glenn Braunstein, M.D., who in the early 1970’s collaborated on the experiments that led to the sensitive assay for hCG, the “pregnancy hormone.” The site is an interesting introduction to a modern technology that is so widespread and easily accessible as to be taken for granted.
