Puppeteer Jerry Nelson, famous for lending his voice to Muppets on “Sesame Street,” “The Muppet Show” and “Fraggle Rock,” died Thursday, according to People. He was 78.

The cast and crew of “Sesame Street,” and the staff of Sesame Workshop, released the following statement in memoriam: “A member of the ‘Sesame Street’ family for more than 40 years, [Nelson] will forever be in our hearts and remembered for the artistry in his puppetry, his music, and the laughter he brought to children worldwide…”

Nelson is, perhaps, best recognized as the voice of Count von Count, a friendly vampire with an unmistakable laugh and an affinity for numbers:
