# Cambridge, Massachusetts in the 1970s

> A dense university city was losing factories, fighting highways, regulating rents, and arguing in public over science and housing.

## Looking around

You stand in a compact city of about 100,000 people[1], pressed between Boston and the river. At Harvard Square, the Red Line still ends here[6], while officials argue over carrying it north to Porter, Davis, and Alewife. Around Central Square and East Cambridge, streets that an eight-lane highway might have cut through remain city streets because the Inner Belt has been rejected[6]. Toward Kendall, the edge of MIT gives onto vacant lots and scattered outposts[2] rather than the later biotechnology district. Houses and apartments carry the marks of a citywide housing fight: many older, non-owner-occupied rentals are under rent control[7]. Public life is close to the surface: city councilors are elected at large by proportional representation[4], and the council chamber can become a place where residents hear scientists argue over recombinant DNA work[3]. The local weekly, the Cambridge Chronicle[5], follows elections, strikes, churches, schools, police, parks, and street scenes.

## Work: Factories fading, universities rising

Kendall Square still shows the old industrial city: vacant land, Draper Laboratories, and the Volpe Center[2] stand where later biotechnology buildings will cluster. Cambridge is already shifting from manufacturing toward services[8], with Harvard and MIT pulling labor, students, clerical work, maintenance, research, and shop trade toward them.

## Home & table: Housing is politics

A renter may live under one of the decade's defining local laws, because older non-owner-occupied rentals are under rent control[7]. The fights are practical and bitter: rents, evictions, condominium conversion, and the Rent Control Board[7] affect who can stay.

## Law & power: Ranked ballots, strong manager

City government is not run like neighboring Boston: nine councilors and six school committee members are elected at large by proportional representation[4], and the city manager handles administration. This structure gives organized minorities a route into City Hall.

## In the air: Science on trial

In 1976, Cambridge becomes a national stage when the council stops recombinant DNA work at Harvard and MIT for review[3]. The argument is not abstract: residents ask whether research inside a dense city can endanger public health.

## What people feared: Roads, labs, displacement

The threat many residents fought was a road: an eight-lane Inner Belt would have cut through Cambridge near Central Square[6]. Another feared danger was invisible, as the city debated possible public-health risks from recombinant DNA work[3].

## Roads & news: A weekly watches everything

The Cambridge Chronicle[5] is the local paper to pick up for elections, strikes, police, fire, churches, schools, parks, Harvard, MIT, and street scenes. Bigger arguments arrive from Boston too, including the school desegregation busing crisis centered across the river.

## Who lived here: Dense and mixed

The census counts 100,361 residents in 1970[1], fewer than ten years earlier. The everyday city mixes students, municipal workers, hospital workers, shopkeepers, tenants, landlords, and people tied to older industry.

## Faith: Churches still visible

Churches are part of the visible civic landscape, since the local paper's 1973 files include churches and church buildings. The opened sources, however, do not give a reliable full map of congregations for the decade.

- **1973** (here): Plans were approved to extend the Red Line from Harvard Square to Alewife through Porter and Davis Squares.[6]
- **1973** (the country): The oil crisis and gasoline shortages became national news that commuters and households in Cambridge would have felt.
- **1974** (nearby): Boston's school desegregation busing crisis began after a federal court ruling.
- **1975** (the world): The Vietnam War ended with the fall of Saigon, a world event still close to campus politics and veterans' lives.
- **1976** (here): Cambridge imposed a moratorium on recombinant DNA research at Harvard and MIT.[3]

## What the sources say

- Cambridge had 100,361 residents in the 1970 federal census, down from 107,716 in 1960. (from the sources)[1]
- The city was fully urban and physically small, so daily life mixed university districts, working-class neighborhoods, industrial blocks, and dense apartment streets. (inferred)
- In the 1970s, Kendall Square near Main and Vassar streets had vacant land after manufacturing declined and firms moved to the suburbs, with outposts such as Draper Laboratories and the federal Volpe Center remaining. (from the sources)[2]
- Cambridge adopted rent control in 1970, applying its initial policy to non-owner-occupied rental housing built before 1969. (from the sources)[7]
- Tenant organizing was one of the decade's central local political activities, as tenants and landlords fought over rents, evictions, condominium conversion, and the powers of the Rent Control Board. (from the sources)[7]
- The proposed Inner Belt was an eight-lane expressway that would have run through Cambridge near Central Square before crossing the Charles River near the BU Bridge. (inferred)[6]
- After the highway fights, Governor Francis Sargent rejected the Inner Belt in 1971 and in 1973 approved extending the Red Line from Harvard Square to Alewife by way of Porter and Davis Squares. (inferred)[6]
- Cambridge used a city-manager government with nine city councilors and six school committee members elected at large by proportional representation for two-year terms. (from the sources)[4]
- In 1976 the Cambridge City Council imposed a moratorium on recombinant DNA research at Harvard and MIT and created a citizens' review process over possible public-health risks. (from the sources)[3]
- The recombinant DNA controversy made Cambridge an unusually visible place for lay citizens to debate the regulation of advanced science. (from the sources)[3]
- The Cambridge Chronicle was the city's newspaper of record, and its 1973 photographs covered city elections, student sports, Rindge Technical School, Cambridge High and Latin, Mount Auburn Hospital, police, fire, strikes, churches, parks, Harvard, MIT, and street scenes. (from the sources)[5]
- Harvard University and MIT shaped employment, street life, housing demand, and politics, but the 1970s city was not only a college town; it also had municipal workers, hospital workers, small shopkeepers, tenants, landlords, and remnants of industry. (inferred)
- Mount Auburn Hospital appears in the local newspaper's 1973 subject files, showing it was a visible Cambridge institution during the decade. (from the sources)[5]
- The Cambridge Chronicle's 1973 subjects include churches and church buildings, but online sources opened here do not give a full denomination-by-denomination map for the decade. (not known)
- Online sources opened here do not give ordinary Cambridge grocery prices, rents by neighborhood, or hourly wages for the 1970s. (not known)
- As across metropolitan Boston, Cambridge residents would have heard constant news about the 1974 Boston school desegregation busing crisis, even though the crisis centered in Boston rather than Cambridge. (inferred)
- The local arts and street scene included the Craft Fair on the Common, Poly Arts Concert, and Arts Proposition Theater, all present in the 1973 Cambridge Chronicle photograph subjects. (from the sources)[5]
- The city was changing from an older manufacturing economy toward services in the 1970s and 1980s, before the later high-technology boom of the 1990s. (from the sources)[8]
