This first paper on the bootstrap is Brad’s most-cited work, currently with some 2,500 citations. A Google search throws up more than 300,000 entries for “Efron, bootstrap.” I think it not an exaggeration to say that the paper started a revolution in statistical methodology. Much of the success of that revolution was due to the rapidity and wide range of consequent developments by Brad and those around him, including several of his Ph. D. students. As Brad has recounted in Efron (2003), his thinking about this topic started in 1972–1973 when he and Rupert Miller left the tranquility of Stanford for sabbatical visits to Imperial College in London. Rupert was finishing his review paper (Miller 1974) and giving talks on jackknife methods, which aroused genuine interest in many of us there. Cross-validation methods were also being talked about–Mervyn Stone presented a paper (Stone 1974) on this topic at the Royal Statistical Society at the end of 1973, but this was focussed on choice1 rather than assessment, which was Brad’s interest. The jackknife and cross-validation methods had both been advocated in a book on data analysis by Mosteller and Tukey (1968), and were again in a second book (Mosteller and Tukey 1977) in the same year that Brad’s paper was presented as the Rietz Lecture at the IMS meeting. Also in the early to mid-1970s there was considerable interest in robust estimation, partly because of Peter Huber’s theoretical work that built on John Tukey’s data analytic inspiration. As Brad reminds us in the 1979 paper, one key product from the robustness area was Louis Jaeckel’s influential 1972 manuscript which elaborated on the idea of an estimate T of a parameter θ as a statistical function T= t (ˆF) estimating θ= t (F), with ˆF the empirical distribution function. This was used in Jaeckel’s development of the “infinitesimal jackknife,” including an extension of the Fisher delta method by which an approximate variance for T could be found if T were a differentiable function of a finite-dimensional average: the empirical distribution function ˆF is just a more complicated average.The original jackknife developed by Maurice Quenouille in the 1950s was a beautifully simple procedure for direct numerical approximation of the bias of a statistical estimate. Then in 1958, John Tukey intriguingly provided the jackknife formula for calculating the variance of a statistical estimate. In the simplest context of one sample, say that the estimate T= t (X) is based on data vector X=(X1,..., Xn) where the Xi’s are outcomes of independent random sampling. Write X (− i) for X with
