We count ourselves unbelievably fortunate to have worked with, been mentored by, traveled with and laughed with Virgil Alan Marple over a significant portion of his professional career.
His creations for the inhalation community include the adult and pediatric Marple-Miller impactors and most recently the NGI. He also trained numerous graduate students as well as entire technical populations, such as the inhaler testing community, in proper impactor design.
