The story began at the Oregon Caves in 1938. After taking a tour, William B. Gruber, an Oregon inventor, met Harold J. Graves, the president of postcard company, Sawyer’s Inc.

Double Visionaries — Graves and Gruber:
‍
Graves asked Gruber about the device he carried consisting of two cameras mounted side-by-side on a tripod. Gruber described his work to create a 3D viewing device. That evening, they met in the Oregon Caves Chateau, and their conversation led to the transformation of Gruber’s invention into the product we know as the View-Master viewer. This 3D viewer was produced by postcard company, Sawyer’s Inc. in Washington County, Oregon for decades. View-Master is now owned by Mattel, Inc.

Gruber personally conceived of and produced many important educational projects, including the “Stereoscopic Atlas of the Human Body,” which contained 221 reels detailing parts of the body. During World War II the U.S. Armed Forces commissioned View-Master reels for use in various training activities.

3D Imaging Over Time:

Sir Charles Wheatstone determined that we see depth from combined views of the left and right eyes. He translated this discovery onto paper prints that were viewed through devices called stereoscopes. Many models of 3D viewers have followed. View-Master offered a small, portable device with a wide variety of reels as well as a camera for consumers to create their own 3D images.

Abert Rim

BEAVER BOARD INFORMATION

Behind you to the east is a steep cliff called Abert Rim, made of many layers of hardened lava flows. This 30-mile-long, 2,500-foot-high, steep cliff is an example of a fault scarp, produced over millennia by great blocks of rock tilting and moving along faults in this region where the earth's crust is thinning and stretching.

The fault that produced Abert Rim is one of many in the Basin and Range Province--a geologic region where rising blocks of crust (horsts) form mountain ranges, and sinking blocks of crust (grabens) create broad basins. The region spans about 300,000 square miles, including almost all of Nevada and parts of Oregon, Idaho, Utah, California, Arizona, and New Mexico.

Lake Abert, in the basin below Abert Rim, covers 63 square miles--but it is only a remnant of Ice Age Lake Chewaucan, which once covered over 470 square miles. Lake Chewaucan's shorelines can still be seen lining Abert Rim's cliffs, far above the present shorelines.

Archaeological evidence shows that Native American have been here for about 11,000 years, with the greatest use between 2,000 and 500 years ago. Most lived in earth covered lodge (pithouse) villages along Lake Abert's shoreline. Artifacts suggest these early people were affiliated with ancestors of the modern Klamath and Modoc Indians, who now live to the west.

Abigail Scott Duniway

In 1860, Abigail Jane Scott Duniway and six other women shocked the town of Lafayette by attending a campaign speech by Col. Edward D. Baker, a U.S. Senate candidate. At that time, most people considered it inappropriate for women to take part in any aspect of political life. Age twenty-six at the time, Duniway’s leadership in the act was the first of countless actions for Oregon’s pioneer of woman suffrage.

STARTING A FAMILY IN LAFAYETTE
During her eight years in the Lafayette area, Duniway took in boarders, and taught at her own Union School. Married to Benjamin C. Duniway in 1853 (the word obey was omitted from their vows), Duniway gave birth to five sons and one daughter. The family moved to Portland in 1871. There, Duniway grew as an activist, publishing an influential weekly human-rights newspaper, The New Northwest, and editing two other papers.

HARD WORK, DETERMINATION AND VICTORY
Mentored by Susan B. Anthony, Duniway attended national conventions and helped form the National American Women Suffrage Association (NAWSA) in 1890. She served as one of NAWSA’s four Vice Presidents at Large. Lafayette was one of the towns where Anthony and Duniway gave speeches on their “Northwest Tour.” Duniway fought for women suffrage victories in Idaho and Washington before Oregon voters approved it in 1912. Governor Oswald West recognized her 42 years of leadership and perseverance when he asked Duniway to write and sign Oregon’s Suffrage Proclamation. It was the first time an equal suffrage proclamation had been written by a woman in U.S. history.

On November 30, 1912, Duniway and Oregon Governor Oswald West signed the state’s suffrage proclamation, which began: “The women of Oregon, after long and patient effort, have persuaded the men of the State to place them on a footing of political equality…”
