Langdon P. Marvin, Jr. '41, one of Harvard's busiest undergraduates, is now a one-man organization and in that capacity is sponsoring Mayor Fiorello La Guardia's speech in the Indoor Athletic Building tonight.

Technically the meeting is being held under the auspices of Phillips Brooks House and the Council of Government Concentrators. But P. B. H., which wanted to get the Little Flower for its government service conference Friday and Saturday, is sponsoring the meeting only to help Marvin out, and the expenses are being footed by an anonymous third party.

Up until last night the Alumni Association, under whose auspices La Guardia is speaking at the Senior dinner in Eliot House tonight, has been acting on the assumption that Marvin represented a large group of undergraduates.

Marvin Only Member

But the Council of Government Concentrators consists solely of Marvin, who was appointed its president last year. It has no other officers or members, and exists "to promote friendly feeling and interchange of views between students and Faculty members" of the Government department.

Founded in 1937, the Council was very active for two years, having a membership of well over 100 at one time. Last year, however, it died a natural death.

Last night Marvin said that there were two other officers: Logan P. Bullitt '41, and Joseph A. Hartman '41. Bullitt, however, denied that he was even a member of the Council, and Hartman said, "Who, me? "I concentrate in Economics."

Treads on Toes

In his efforts to revive the Council by staging a spectacular La Guardia meeting, Marvin has trod on the toes of several other organizations: Brooks House, the Dunster House Forum, and the Alumni Association.

Brooks House, which for months has been trying to get Mayor La Guardia for tomorrow or Saturday, attempted to join forces with Marvin, but was double-crossed. A Brooks House official last night said that their relations with Marvin had been "highly unsatisfactory."

The Dunster House Forum, at which Marvin is slated to speak after he gets through sponsoring La Guardia, is sore because the Mayor's speech conflicts with the Dunster meeting which was scheduled long ago.

And Marvin nearly put a crimp in the Alumni Association's plans for tonight's dinner, when La Guardia, scared by the thought of so many specifies in one evening, almost decided not to come to Cambridge at all.
