Engineering accepted their first students, the SSRC Data Bank (later renamed the UK Data Archive) was established and the Lecture Theatre Building and Library opened along with the first phase of the Social and Comparative Studies building, while work proceeded on Tawney and William Morris residential towers. The Protests of 1968 Amid the worldwide escalation of social conflicts and protests against the Vietnam War, the University of Essex was at the vanguard of the 1960s student uproar. In March 1968, a demonstration against the visitation of the then Shadow Secretary State for Defence, Enoch Powell, received national publicity whereby seven students were summoned to disciplinary hearings to which was ultimately prevented by student sit-ins. On Tuesday, 7 May 1968, Dr Thomas Inch from Porton Down paid a visit to host a lecture at the university. In a carefully planned demonstration, an indictment was read as Dr Inch began to speak citing chemical and biological warfare activities at Porton Down. Police intervention upon the call of the university was superseded by an insurmountable number of students who managed to prevent arrests. On Friday, 10 May 1968, three students; Pete Archard, Raphael Halberstadt and David Triesman (now The Lord Triesman) were suspended and ordered off the campus. No evidence or charges were notified to the students, and no opportunity was given for the students to present their defence. The university's magazine, Wyvern, reported that on Monday, 13 May, "Students picket all entrances to the university from early morning distributing leaflets calling all students and staff to meeting to discuss suspension of the three students. A huge meeting attended by nearly all the university population, voted overwhelmingly to refuse to participate in the university – in its place a Free University was declared ". After a week the three students were reinstated. Many Essex students joined protests in Paris over the summer of 1968 and unrest on the Colchester campus continued into 1969. The 1970s and 80s Within the frame of the 1970s to the 1980s, the university expanded by installing a health care centre, day nursery, bookstore, exhibition gallery and constructed new student residences. The School of Law, Human Rights centre, Department of Philosophy and the Department of Biological Sciences were opened. In the late 1970s to the early 80s, the university began concentrating its teaching into large departments. Cooperation with local companies were forged allowing the university to secure vital research
