passed away yesterday morning (27th November). Richard began his sand
fly journey with Ralph and myself in Belem and his keen insight into the
longipalpis complex paved the way to our understanding of this
tremendously important vector. His pioneer work on its colonization and
artificial feeding led to the first experimental transmission of
Leishmana infantum chagasi that was published in Nature. His friendship,
kindness, patience and good humor will be remembered by his many
friends and students. <div> <span name="x"></span><br></div><br></div></body></html>
