History of OMSI

The concept of OMSI was born more than 100 years ago in the mind of famed naturalist C. Hart Merriam.

In 1906, a City Hall Museum was established for displaying some of the amazing collections received from local donors. Despite public demand, by the 1930s these exhibits had been placed in storage due to the need for more office space in the building. An effort in 1930 to start a Portland Museum of Natural History was soon derailed by the Great Depression. Then, in 1938, Portland civil engineer J.C. Stevens joined the museum effort when he was appointed chairman of the Geological Society of the Oregon Country's museum committee. Stevens remained one of the museum's strongest advocates for the rest of his life, serving as both President and Board member throughout the years.


Due to delays caused by the Second World War, it was not until 1944 that the idea of a museum began to take shape with the incorporation of the Oregon Museum Foundation. In 1946, the first display of natural history objects was exhibited by the Foundation at the Portland Hotel. Support for the museum continued to grow and in 1949, businessman Ralph Lloyd allowed the Foundation to set up a temporary museum in a house he owned on NE Hassalo Street. It was in this location that the museum was first given the name "Oregon Museum of Science and Industry." Within a year, the Pacific Northwest's first public planetarium opened on the site, giving visitors the chance to take a 20-minute trip to the stars under its dome.


By 1955, annual attendance at the Hassalo House had swelled to more than 25,000 but the house was set to be demolished to make way for a new hotel. The house had always been considered a temporary home and there were very early plans to build a dedicated museum building, but the museum had no land to build on. The City Council stepped forward and agreed to lease land in Washington Park to OMSI for the sum of one dollar per year.


Now that a location had been found, a group of civic-minded business and education leaders began a statewide fundraising campaign to build the new museum of science and technology. In the spirit of pioneer barn-raisings of the 19th century, more than 400 volunteer union brick layers and hod carriers laid 102,000 bricks to raise the walls of OMSI's new Washington Park site in one day on August 17, 1957. On June 7, 1958, J.C. Steven's dream of a dedicated hands-on museum of science and technology became a shining reality with the opening of the Washington Park location. Over the next 35 years as a non-tax based private institution, OMSI's interactive science exhibits and educational programs introduced millions of visitors to the wonders of our world.


By the mid-80s, OMSI's popularity with visitors surpassed the size of its facility as 600,000 people per year attended a museum built to accommodate only 100,000. A new group of community leaders began a campaign to build a state-of-the-art science center, complete with a 315-seat dome-screen OMNIMAX Theater (the first in the Northwest) and an expanded 200-seat planetarium. Five years later, businesses, foundations, and individuals donated more than $32 million to construct a new museum. The project came together when longtime OMSI supporter, Portland General Electric, generously donated an 17-acre site that held a historic sawdust-fired power generation plant.  The plans for the new museum incorporated the original smokestack and turbine buildings to blend together technology of the past, present, and future.


On October 24, 1992, the new 219,000 square-foot OMSI opened. In 1994, OMSI opened the USS Blueback for public tours, providing a unique look at the people, history, and technology associated with the last non-nuclear powered submarine built by the U.S. Navy. OMSI has continued to grow over the years and currently has five exhibit halls with hundreds of interactive exhibits and displays. Today, the museum serves more than one million visitors at the museum and through off-site education programs. OMSI is ranked as one of the top science centers in the United States and has an international reputation for its innovative exhibits and educational programs.

OMSI science camps take place in a number of venues including State and National Parks, private camps, as well as backcountry wilderness areas throughout Oregon, Washington, California, and even Canada.  OMSI Science Camps are the perfect way to develop skills and enthusiasm while instilling curiosity and respect for the natural world.  Hancock Field Station, a residential camp located in the John Day Fossil Beds National Monument near Fossil, Oregon, has been owned and operated by OMSI for over 60 years. Other OMSI camps are held at locations around the Pacific Northwest including Wolf Creek Educational Center in the Redwood National and State Park in Northern California, and San Juan Island National Historic Park on San Juan Island, Wash. OMSI’s newest residential camp, Camp Gray, is located in Newport, Oregon.

Camps are offered for youth grades 2-12, as well as adults and families.  Camps run during Spring Break and from the middle of June through August and generally last one week.  Campers are immersed in a positive and wholesome environment where self-esteem, confidence, teamwork and friendships develop naturally, and adventure and activity are balanced with quiet and reflective moments.

Camps are science-oriented with hands-on activities designed to be active, fun and educational.  Campers can sign up for naturalist, adventure, and/or research camps.  Campers become explorers, learn about marine biology, or take a rafting trip along the Deschutes River.  The safety and success of each participant is taken to heart by a caring, professional staff of outdoor and science educators and all programs maintain a ratio of one adult for every five to six participants.


With the widest variety of science topics offered compared to other programs in the Northwest, youths aged 4-14 can take part in sequential, in-depth study in one or more of their favorite fields of science.  OMSI offers a high-caliber staff as all instructors are Oregon State certified teachers and/or have extensive experience working with children. 

In OMSI Science classes, young scientists investigate scientific phenomena using a hands-on approach.  They design and create their own inventions and experiments, interpret data, control variables, present conclusions and develop new thinking strategies while they gain lifelong learning skills and attitudes.

Spring Break classes run in March, and week-long summer classes are offered from mid-June to late August for children ages 4-14.  Classes run all day and are geared towards each age group.  Classes are held at OMSI’s Water Ave location and Jesuit High School.


OMSI offers “camp-ins”, in which participants can spend a night at the museum.  Camp-Ins are a great idea for schools, clubs, church, scout, or youth groups of any size.  At the Museum Camp-In, overnight visitors have full access to the entire museum, enjoy a film at the Empirical Theater, tour the submarine, engage in hands-on science activities, enjoy dinner, an evening snack and a continental breakfast, and participate in fun, action-packed activities. Museum Camp-Ins are geared toward either elementary or middle school students.

In Submarine Camp-Ins, students from grades 3-12 sleep aboard the USS Blueback submarine, where they explore the control room, peer through a periscope, check out the engine room and set a course to carry out a top-secret mission.

OMSI’s Harry C. Kendall Planetarium, a 200-seat, 52-foot domed theater, is one of the most technologically advanced planetariums in the Pacific Northwest, hosting over 100,000 visitors annually.  We strive to create an inspiring and unique visitor experience through the novel and immersive environment of the planetarium theater.  Fully integrated within OMSI’s mission, the Planetarium experience is made possible through current information of space science and advances in theater technology.

The planetarium sports the new generation of Sky-Skan’s DigitalSky simulation and control system, DigitalSky Dark Matter. Designed by planetarium directors for planetarium directors it constantly updates as new capabilities and content arrive from the cloud. 

DigitalSky Dark Matter uses the JVC Reference Series offering an ultra-deep 160,000:1 native contrast ratio and 2,000 lumens per projector. A server of computers with the latest in NVidia graphics, 8GB RAM, 2TB memory, solid state drives, and 3.7GHZ Quad-Core processing per PC powers the Definiti system, including fulldome projection, sound system integration, and master control.

The laser show installation at OMSI uses six Rainbow FX laser projectors from the new Laser Fantasy Rainbow FX laser system. The laser system outputs about 15 watts of laser light compared to less than three watts from the previous system, and uses a fraction of the electricity eliminating the need for three-phase power and water cooling. 

Over the last four decades, the OMSI planetarium has built a library of more than 125 full length, high quality shows, spanning educational topics, classic rock, and modern hits. Combined with our terrific hardware, it’s our shows that keep the audience coming back year after year.

USS Blueback Submarine

The USS Blueback (SS 581) is one of the most modern U.S. submarines on public display anywhere in the country.
Download Press Kit

The ship was decommissioned in October 1990.  It was opened to the public in May 1994 at OMSI, and is on permanent display at OMSI’s dock on the east side of the Willamette River.

Visitors can climb aboard the sub and experience what life was like for the 85 men who lived and worked on the boat.  40-minute tours occur throughout the day, and include a behind-the-scenes look at how a submarine dives, produces its own electricity and fresh water, and stays submerged for months at a time.  Highlights of the tour include a look at the engine room, the radio room, the control room and attack center, the crew quarters, and the escape and torpedo-loading trunk. 

A more technical tour of the sub takes place on the first Sunday of every month. The purpose of the two-hour “Guided Tech Tour,” guided by an ex-submariner, is to give visitors a comprehensive technical look into the workings of the submarine.

Kids can also spend the night onboard the sub, as part of OMSI’s camp-in program.  Students from elementary through middle school sleep in the crews’ bunks, after they explore the control room, peer through a periscope, check out the engine room and set a course to carry out a top-secret mission.

The Blueback also features a volunteer HAM radio station (W7SUB) operated by retired Navy veterans.  They communicate with other HAM radio operators throughout the world.

OMSI hosts two memorials for submariners on eternal patrol.  One is a permanent memorial plaque for submarine veterans of WWII and is located at the entrance to the ramp leading to the dock.  The other is the propeller (screw) from the Blueback, surrounded by 67 bricks, each engraved with the name and date of a lost U.S. submarine.  It is located on the river walkway in front of the museum.

In 2014 OMSI’s sub volunteers were honored with an award from the Association of Fundraising Professionals (Oregon and SW Chapter) for their tireless dedication.
