Credits: past and present staff involved in eRA

The e-RA database was initially developed by Jackie Potts, Andy Caiger, Kevin Crowley, Sharon Brown, Paul Verrier, Christine Thomas, Roger Payne and Joe Perry, with funding from the Lawes Agricultural Trust and the Leverhulme Trust. Alan Todd and Gill Tuck subsequently prepared and curated the data, with Bill Moore responsible for the software and database application development.

e-RA has further been considerably developed as part of the Long-Term Experiments National Capability (2017-2023) and since 2023 as part of the the National Bioscience Research Infrastructure (NBRI). This current website and data portal specifically, has been developed by the e-RA Team* consisting of the e-RA Curators, Software & Web Developer under management of the Agroinformatics Project Leader. The e-RA team* are part of the RLTE-NBRI team**.

The data made available through this portal by the e-RA team are at the end of a sequence of providers starting with the LTE manager, the Farm Staff, the Sample Collectors, the Sample Processors and Statisticians. The data and the website are a window into the Rothamsted Research Long-Term Experiments and associated data, and is the result of decades of work by many science and non-science staff and others. The list of past staff is not complete, there are many generations of past staff who have been involved in the Rothamsted long-term experiments, we are indebted to them all but have been unable to find and list all who have contributed.
