SOLVAY, N.Y. Walk into the Solvay Public Library on a Tuesday morning and the first thing you notice is the Mertens portrait. Cornelia Mertens, librarian here from 1911 until her retirement, hangs near the circulation desk beside a second Mertens portrait, both anchored to the village’s early-twentieth-century civic life. Down the hall, past the children’s room, is a small space with a quiet name: the Solvay Process Room. It opened the year after the soda ash plant a mile away dismissed roughly 1,400 people in 1985 and started tearing itself down.
That is the village in a single building. A 1905 Carnegie library still operating five mornings a week. An archive room dedicated to the chemical works that paid for half of it, donated by the corporate descendant that walked away from the village in 1985. Across town, the Solvay Process Co. site is grass now, capped under state order. The library opens at 10 a.m.
A library Andrew Carnegie helped pay for
The Solvay Public Library was chartered by the New York State Board of Regents on May 21, 1903. A board of trustees first met on April 13 of that year, three village men named Frederick Hazard, George J. Schattle, and Charles D. Richards. Hazard was a member of the family that owned the chemical works, and his presence on the founding board is the entire story of how a 1,400-person village got a building like this. Construction ran 1903 through 1905. The architect was James A. Randall of Syracuse, who produced a one-story Classical Revival building on a high basement, with a hipped roof, a distyle-in-antis portico in the Ionic order, and a 1.1-acre footprint at 615 Woods Road.

The funding mix tells you how Andrew Carnegie’s library program actually worked. Carnegie put up $10,000 on the standard condition that the village commit to ongoing operating support. The Solvay Process Co. itself covered the rest. The first appointed librarian was O. Ware Clary, who served from 1904 until his retirement in 1911. Cornelia Mertens, his assistant, took over. The Mertens portraits are still on the wall. Daniel W. Casey, a longtime trustee, got the community room named for him in 1991 in recognition of years of unpaid service to a building most villages this size do not have.
The library was listed on the National Register of Historic Places on October 31, 2007. It is one of the oldest continuously operating Carnegie libraries in New York State. A 1979 renovation cost more than $243,000 in combined federal and local funds. In April 2008 the village completed an addition with a new elevator. None of this is museum work. Story hour, which began here by 1916, still runs. The library joined the Onondaga Library System on January 1, 1962, and has stayed in.
The plant the village was named after
William B. Cogswell, a Syracuse civil engineer, and Rowland Hazard II, a Rhode Island industrialist, founded Solvay Process Co. in 1880 in partnership with the Belgian chemists Ernest and Alfred Solvay. The brothers had patented the Solvay process in 1861, a method for making sodium carbonate from brine and limestone. Soda ash was the workhorse chemical behind glass, paper, soap, and detergents, and Onondaga Lake sat on a brine deposit that the Indigenous and colonial salt industries had been working for two centuries. Cogswell saw the geology, traveled to Belgium, and brought the technology back to New York.
The plant opened in 1881 on the lake shore. By 1884 it was producing about 20 tons of soda ash per day. The village incorporated in 1894 and took its name from the works. At peak the plant employed roughly 1,400 people. It was the kind of place where a third of the village was on payroll, where the company built housing, sponsored civic clubs, contributed to the library, and stamped its name on the geography. Frederick Rowland Hazard succeeded his father as president. Louis Semet developed the coke oven technology that became a sister business. William H. Nichols, the chemist, helped promote the 1920 merger that turned Solvay Process Co. into part of Allied Chemical & Dye Corporation.
The plant made soda ash, caustic soda, chlorine, calcium chloride, refined bicarbonate, and the byproducts that would shape the village’s afterlife: calcium chloride slurry pumped onto the lake shore, more than 400 acres of it, building up wastebeds that are still there. Mercury cells came online in 1950 for chlorine production. The federal government estimated that by 1970 the plant was discharging roughly 25 pounds of mercury per day into Onondaga Lake, which is when the U.S. Attorney General sued to stop it. The fishing ban arrived the same year.
The 1985 closure
Allied Corporation merged with the Signal Companies in 1985 to form AlliedSignal Inc. The same year, the new company announced the closure of its Syracuse Works. The number cited was $55 million in losses over three years. The number that mattered in the village was roughly 1,400 jobs. Demolition crews were on site within months. The chemistry, which had named the village and the company, moved to a newer AlliedSignal plant in Green River, Wyoming, where natural trona deposits made the same product cheaper than anyone could pump it out of Onondaga brine. The Solvay process at the Solvay plant was outcompeted by Wyoming geology.
The 1985 announcement ranked alongside contemporaneous shutdowns at General Electric in Auburn and at Chrysler in Syracuse as one of the worst industrial losses Central New York absorbed in that decade. The Solvay-Geddes Historical Society still posts an anniversary note every spring. The Solvay Public Library opened its Solvay Process Room the following year specifically to house the corporate archive Allied donated on the way out: photographs, blueprints, payroll books, the company newsletter, the kind of material that gets dumpstered when a plant goes down unless somebody walks across the street and asks for it.
What replaced the plant
The lakeshore site sat as an industrial fossil for three decades. New York State Department of Environmental Conservation orders eventually capped the wastebeds. Honeywell, which inherited the cleanup obligation after merging with AlliedSignal in 1999, paid for two-foot soil covers in active recreation areas and one-foot covers in passive zones, planted native vegetation, and partnered with Onondaga County on the project that anyone who has driven to a concert in Geddes knows: the 17,500-seat Lakeview Amphitheater. Construction broke ground in November 2014. The venue opened on September 3, 2015. Miranda Lambert was the inaugural act, playing her Roadside Bars and Pink Guitars tour on a portion of Wastebed 5.
The wider cleanup ran on a different scale. Honeywell signed a federal consent decree in 2006 for an estimated $451 million plan to dredge roughly 2.65 million cubic yards of contaminated sediment and cap about 579 acres of lake bottom. Governor Cuomo announced completion of the capping in 2017. The amphitheater is built on what that cleanup made buildable. It also exposes the limit of what wastebed land can host. There are no permanent restrooms on the wastebed proper because plumbing trenches would breach the cap, which is why portable toilets are standard on concert nights. Concertgoers are advised against wandering in the brush around the venue. Engineers built the site to keep industrial residue down, not to make ground that someone could pour a foundation on.
The village that stayed
Solvay’s population was 7,986 in 1930. By the 1980 Census, the closest snapshot before the closure, it was 7,140. By 2000 it was 6,844. By 2020 it was 6,645. The trajectory is not collapse. It is the slow attrition of a village that lost a third of its payroll and held the rest of itself together. Onondaga County’s urban core has been losing residents for sixty years and its outer suburbs have been gaining them. Solvay is neither category. It is a 6,500-person village that kept its housing stock, kept its schools, kept its public library, kept its identity, and is now somewhere on its second life.
What kept it intact was a combination of accidents and decisions. The brick and frame housing built for plant workers in the late 19th and early 20th centuries was solid stock that did not depreciate to the point of demolition. The Solvay Union Free School District consolidated rather than collapsed; the Solvay Tigers football and baseball programs still draw regional notice. About 35 percent of village residents in 2005 identified as Italian American, a community that arrived in waves to work the plant and built the parish life and social clubs and old-school sub shops that anchor Milton Avenue. More recent Ukrainian families have done the same on a smaller scale. The location helped. Solvay sits at the intersection of Interstate 690 and Route 695, six minutes from downtown Syracuse, which kept it commutable when other former mill villages farther out lost their commuter base.
Mayor Derek Baichi made bringing back Field Days a campaign goal in his first term. The summer festival had run as an annual tradition through the 1980s, 1990s, and 2000s, but funding collapsed and the event went dark in 2011. Lori Volski ran the 2019 revival, which landed August 16 and 17 with a parade Saturday morning at 11:30 and a fireworks display at 10 p.m. that drew people from Geddes and Onondaga Hill who had not been to a Solvay parade in seven years. Field Days has run every year since, now branded Solvay-Geddes Field Days, with the 2025 edition held in August. The State Fairgrounds, a few blocks east, still host the New York State Fair every August. The amphitheater, two miles north along the lake, brings outsiders into the village on concert nights, although most of them never see Woods Road.
A library, a plant, and a question
Forty years on from the 1985 closure announcement, and 121 years after the Carnegie library opened, the two buildings together pose a question the village has been quietly answering for four decades. The library was civic infrastructure paid for in 1903 by a Belgian-process chemical works that, in 1985, decided it could not afford to make soda ash on the shore of Onondaga Lake anymore. The infrastructure is still here. The works are not. What does a single-industry village owe to its industry once the industry is gone, and what does it owe to itself?
The practical answer is maintenance. The library’s 1905 fabric needs steady capital reinvestment, which a 6,645-person tax base can absorb only with state library construction grants and occasional Carnegie Corporation of New York programmatic support. The wastebeds need Honeywell’s ongoing commitment, which is enforced by NYSDEC consent orders rather than by goodwill. The village needs its own reinvention, one budget cycle at a time, into something other than a one-company town.
What Solvay has not done is pretend the plant is coming back. The closure was final. AlliedSignal moved the chemistry to Wyoming. Honeywell inherited the liabilities. The wastebeds were capped. The amphitheater opened on land where the works once stood. The library, meanwhile, opens at 10 a.m. on weekday mornings the way it has since 1905. The Ionic columns, the hipped roof, the 1.1-acre footprint at 615 Woods Road. It is the most enduring civic artifact the Solvay Process Co. ever paid for, and the one still plainly useful. The Mertens portrait is still on the wall. Story hour still happens. Forty years after the plant left, that durability is its own argument for what a village is.
