AbstractJohn Blake (1947â€“2016) was a leader in fluid mechanics, his two principal areas of expertise being biological fluid mechanics on microscopic scales and bubble dynamics. He produced leading research and mentored others in both Australia, his home country, and the UK, his adopted home. This article reviews John Blakeâ€™s contributions in biological fluid mechanics, as well as gives the authorâ€™s personal viewpoint as one of the many graduate students and researchers who benefitted from his supervision, guidance and inspiration. The key topics from biological mechanics discussed are: â€œsquirmerâ€ models of protozoa, the method of images in Stokes flow and the â€œblakeletâ€ solution, discrete cilia modelling via slender body theory, physiological flows in respiration and reproduction, blinking stokeslets in microorganism feeding, human sperm motility and embryonic nodal cilia. doi:10.1017/S1446181118000020
