As Ifakara Health Institute (IHI) celebrates its 70th anniversary, we look back at the leaders who have helped shape its journey from a small research centre into one of Africa's leading health research institutions.

Since its establishment in 1956, Ifakara has grown significantly, contributing to important discoveries, training generations of scientists and helping improve health in Tanzania and beyond.

Behind this progress are directors who, over the years, have guided the Institute, built strong partnerships and helped it grow into what it is today.

The early years: Building a strong foundation

Among the earliest directors in Ifakara's records were Gerhard Eichenberger (1975–1977), Adrian Zumstein (1978–1981) and Prof. Marcel Tanner (1981–1984).

Their leadership helped lay the groundwork for Ifakara's growth, particularly by strengthening research activities and relationships with international partners, including institutions in Switzerland.

They were followed by Don de Savigny (1985–1987), Christoph Hatz (1987–1988) and Calum MacPherson (1988–1989), who continued building on these foundations and supporting the Institute's scientific work.

Growing into a leading research institution

During the 1990s, Thomas Teuscher (1990–1994) and Andrew Kitua (1994–1997) led Ifakara through another period of growth.

Hassan Mshinda (1997–2006) later took over, serving for nine years as the Institute continued expanding its research activities and strengthening its position in Tanzania's health sector.

He was followed by Prof. Salim Abdulla (2008–2016), whose leadership came during a period when Ifakara was increasingly involved in major health research, particularly studies on malaria, vaccines and ways to prevent diseases.

A new generation of leadership

More recently, Dr. Honorati Masanja (2016–2026) led the Institute for a decade, overseeing continued growth in research, partnerships and institutional development.

In September 2026, Dr. Ally Olotu took over as Chief Executive Director, beginning a new chapter in Ifakara's history.

His appointment comes at an important time as the Institute celebrates 70 years of achievements while preparing for the opportunities and challenges ahead.

Celebrating the people who helped build Ifakara

From the early vision of Prof. Rudolf Geigy, whose work helped establish Ifakara in 1956, to the directors who followed, each generation of leadership has played a part in shaping the Institute.

Their contributions can be seen in the research facilities, scientific partnerships, discoveries and generations of researchers that make up Ifakara today.

Of course, this journey has not been shaped by directors alone. Scientists, fieldworkers, support staff, communities and partners have all contributed to the Institute's success.

As we celebrate 70 Years of Impact: Roots, Reach, and What's Next, we recognize the directors who have helped guide Ifakara through the decades and the many people who have worked alongside them.

Different leaders, different generations, but one shared goal: using science to improve people's lives.
