According the the NYT report,
Four Arab-Americans claimed to have invented the ice cream cone
And how many created the falafel?
But, to be fair, here's what one source claims:
The first true edible conical shaped cone for serving ice cream was created at the St. Louis Worlds Fair by Ernest Hamwi in 1904. His waffle booth was next to an ice cream vendor who ran short of dishes. Hamwi rolled a waffle to contain ice cream and the cone was born. Hamwi was of Syrian descent and holds Patent 1,342,045 issued June 1, 1920.
But this site gives a more in-depth historical over-view which points to Italian and English origins even if the four Arabs seem to have the modern patent claim, er, wrapped up.
And as for falafel, see this (no link)

origin is uncertain, it is believed that it originally came from India, where it was made with spiced soured bread. The word "falafel" comes from the Arabic word فلفل (filfil), meaning pepper, and probably ultimately from Sanskrit pippalī. Falafel (at least the Middle Eastern style) is made from field beans, chick peas or any combination of the two. The Egyptian variation exclusively uses fava beans, while other variations may exclusively use chick peas. What makes falafel different from many other bean patties is the beans are not cooked prior to use. Instead they are soaked, possibly skinned, then ground with other ingredients and deep fried.
My friend Ilana Brown pointed out to me this sentence in the article on the museum:
"There have been significant populations of Arab Jews in Iraq, Yemen, Syria, Egypt and Morocco," the museum notes. That ancient world (which until the 1940's included more than 900,000 Jews) is represented by a photograph of a Tunisian synagogue - the same one, the exhibit fails to mention, that was bombed by Al Qaeda operatives in 2002.
And what the NYT fails to mention is that the date "the 1940's" is a euphemism for the establishment of the state of Israel which led to a policy of forced emmigration from those countries.
