Jonathan Finlay

Jonathan Lester Finlay was born in Manchester, England, on 16 October 1948, the only son of Minnie and Mark Finlay. He grew up with two older sisters, Margot and Isolde, and was close to both. Isolde died young of lupus when Jonathan was nine years old. His family says this tragedy was one of the main reasons he decided to become a doctor, hoping to find cures for terrible diseases and to help people. Family photographs shared after his death include his bar mitzvah.

Finlay attended Carmel College in Wallingford, Oxfordshire. He studied at the University of Birmingham from 1967 to 1973, earning a BSc with honours in biochemistry in 1970 and the medical degrees MB, ChB in 1973. He completed internships and residencies in paediatrics in Birmingham, including paediatric oncology under Dr. Jill Mann. In 1976 a senior residency at the Christie Hospital and Holt Radium Institute in Manchester, under Dr. Patricia Morris-Jones, set the course of his career in paediatric oncology. He then trained at the University of Wisconsin-Madison as a fellow in paediatric immunology under Dr. Richard Hong (1976 to 1978) and in paediatric haematology and oncology under Dr. Nasarollah Shahidi (1978 to 1980). He was later elected a Fellow of the Royal College of Physicians of London (2012).

Between 1980 and 2003 Finlay held faculty posts in paediatric oncology at Stanford University (1980 to 1982), the University of Wisconsin-Madison (1982 to 1987), the Children's Hospital of Philadelphia and the University of Pennsylvania (1987 to 1989), Memorial Sloan Kettering Cancer Center and Cornell University (1989 to 1997), and the Stephen Hassenfeld Children's Center at New York University (1997 to 2003). He served as vice-chair of the Department of Pediatrics at Memorial Sloan Kettering, director of the Pediatric Oncology Program at NYU and director of the Neuro-oncology Program at the NYU Comprehensive Cancer Center.

From 2003 to 2014 he directed the Neuro-oncology Program at Children's Hospital Los Angeles and was professor of pediatrics at the Keck School of Medicine of the University of Southern California, where in 2013 he was appointed to the Audrey and Billy Wilder Chair in Neuro-oncology. On 1 July 2014 he became director of neuro-oncology at Nationwide Children's Hospital in Columbus, Ohio, and a tenured professor of pediatrics at The Ohio State University College of Medicine. In 2015 he was named to the Elizabeth and Richard Germain Endowed Chair in Pediatric Cancer. He led the programme until 2020 and became emeritus professor of pediatrics and radiation oncology at Ohio State. From January 2024 he worked part time as a community general paediatrician in Pismo Beach, California, while continuing to advise on early childhood embryonal tumours, choroid plexus carcinomas and central nervous system germ cell tumours.

From 1990 Finlay was principal investigator of the Head Start series of clinical trials for young children newly diagnosed with malignant brain tumours such as medulloblastoma. Head Start I ran from 1991 to 1997, Head Start II from 1997 to 2003, and Head Start III from 2003, together involving more than 40 institutions. The trials used intensive induction chemotherapy followed by marrow-ablative, high-dose chemotherapy with rescue using the child's own previously harvested blood stem cells, with the aim of curing the tumour while avoiding or reducing cranial and craniospinal radiation.

Nationwide Children's Hospital said Head Start was the first programme to investigate and endorse high-dose chemotherapy with bone marrow transplant for young brain tumour patients, and that the approach became the standard of care for young children with many types of malignant brain tumours. Head Start 4, hosted by the Nationwide Children's NEXT Consortium and open at dozens of sites in the United States, Canada, Brazil, Australia, the United Kingdom and New Zealand, was a randomised trial that used molecular risk profiling to tailor therapy and also studied hearing, neuropsychological, hormonal and growth outcomes.

Finlay was married to Adriana Maria Finlay of Uberaba, Brazil. He had a daughter, Anna Victoria Finlay, who works in fashion in New York City, and he was an uncle to several nieces and nephews in England and Brazil. He remained close to his sister Margot, despite living on opposite sides of the Atlantic, until her death in 2018. He and Adriana lived in New York, in Columbus, Ohio (including Worthington), and in Nipomo, California, with their dogs Boris, Zoe, Wolfie and Lili. In 2026 they moved to Uberaba, where he was learning Portuguese and cooking Brazilian dishes, especially from Minas Gerais. His listed pastimes were wine tasting, cooking, films and opera.

Finlay believed that curing a child was not enough if treatment left the child with lifelong harm. He argued that young children with malignant brain tumours should be treated hard and early with chemotherapy so that radiation could be avoided, and he described ultra-high-dose chemotherapy with marrow rescue to families as like getting a year's worth of therapy in six days. He said his ideas were met with significant scepticism for years. He also believed advances should reach children everywhere, and he devoted much of his later career to training and outreach in low and middle income countries.

Colleagues credit Finlay with changing the standard of care for very young children with malignant brain tumours and with putting quality of survival alongside cure as a goal of treatment. The International Society of Paediatric Oncology called him a visionary leader and a giant of paediatric neuro-oncology. The Society for Neuro-Oncology said his legacy lives in the children he fought so hard to preserve. His mentorship shaped a generation of paediatric neuro-oncologists around the world, and his international outreach work, beginning with SNO's International Outreach Committee, helped bring modern brain tumour care to places with limited resources.

2001: Society for Neuro-Oncology Award for Excellence in Pediatric Cancer Research. 2012: Elected Fellow of the Royal College of Physicians of London (FRCP). 2012: Society for Neuro-Oncology Award for Excellence in Pediatric Cancer Research. 2015: Elizabeth and Richard Germain Endowed Chair in Pediatric Cancer, Nationwide Children's Hospital. 2016: International Achievement Award, Society for Neuro-oncology of Latin America (SNOLA). 2019: Society for Neuro-Oncology Lifetime Achievement Award, the first given to a paediatric specialist. 2022: International Symposium on Pediatric Neuro-Oncology Lifetime Achievement Award.

Finlay wrote or co-wrote more than 350 peer-reviewed papers, review articles and book chapters, and from 1985 delivered more than 380 invited lectures, mainly on childhood brain tumours. He sat on the editorial boards of several medical journals and on the advisory boards of childhood brain tumour charities. His life story featured in the International Brain Tumour Alliance's Brain Tumour Magazine in 2014 under the title The English Patient Who Was Also a Doctor. He appeared in Nationwide Children's Hospital films about Head Start and in the This Week in Pediatric Oncology podcast, where he reflected on his career.

Jonathan Finlay died on 24 October 2026, aged 78, according to a statement from his family. Some early reports and Wikipedia gave 26 October, the day the news spread, but the family statement and memorial site give 24 October. His family says that late in life he faced a renewed battle with cancer with extraordinary courage, but a formal cause of death was not announced and the place of death was not stated. Tributes were published by the International Society of Paediatric Oncology, the Society for Neuro-Oncology and the IronMatt foundation, and his family created an online memorial with a guestbook. He is survived by his wife Adriana, his daughter Anna Victoria, family in England, the United States and Brazil, and his four dogs.
