The Philip Frankenheimer whom Windmuller found to be unhelpful may have been the father of a man which whom he associated in coming decades. A New Yorker named Philip Frankenheimer became fairly well known in the second half of the nineteenth century for many of the same liberal causes which Windmuller supported. In 1880 they both served as officers of an ad hoc group of German-Americans who opposed Ulysses S. Grant's bid for a third term as President. (See "Not in Favor of Grant; Germans Protesting Against the Third Term", New York Times, February 24, 1880, Page 2)

This Philip Frankenheimer was prominent in Jewish affairs as well as local politics. In 1863 he served on the building committee for construction of an "Asylum for Orphan Jewish Children." The New York Times covered the ceremony for dedicating the new building. Here's the lede of the long article: "The Asylum for Orphan Jewish Children recently erected on Seventeenth-street and Third-avenue, was yesterday dedicated, with appropriate ceremonies, to the purpose for which it is intended. The occasion was of more than ordinary interest to the Jewish residents of New-York, and they gathered in great numbers to witness, and by their presence add importance to the act of inauguration. All the wealth and high respectability, all the beauty and the fashion of which the sons and daughters of Israel who have cast their lot in this community possess so largely recognized a share, were represented in immense force, and the number of the general multitude could not be calculated at less than several thousands. Unlike mos affairs of the kind, in which the spectators are chievly attracted by curiosity, all in this case seemed brought together by feelings of personal pride in the success of the undertaking, and by that strong bond of sympathy which keeps a people of peculiar race and religion specially united in a land of their adoption." (The Hebrew Orphan Asylum, NYT, November 6, 1863, Wednesday, Page 2.) Frankenheimer was also listed as a patron of the asylum in a state report issued in 1881. (Report of the Hebrew Orphan Asylum of the City of New York.)

In 1862 he helped organize a mass meeting to support the Federal goverment in the Civil War. (proceedings at the mass meeting of local citizens on union square, new-york 1862. "The citizens of New-York, of all parties, who are for supporting the Government in the prosecution of the war and the suppression of the rebellion, are requested to meet on Union Square, on Tuesday afternoon next, 15th insi, at 4 o'clock, to express, without reference to any party question whatever, their undiminished confidence in the justice of our cause, and their inflexible purpose to maintain it to the end, and to proffer to the Government all the aid it may need to the extent of all their resources.")

In 1869 he was a trustee of the Association for Improved Instruction of Deaf Mutes. (Documents of the Assembly of the State of New York, Volume 15.) And in 1873, a member of the Liberal Republican General Committee pressing for political reform in the City and State. NY Tribune, 1873.)
