Within the text
Here, by starting your sentence by referring to Henderson, you're making him a more important source in your text. E.g.:
According to Henderson (1969: 25) "Universities are the guardians of intellectual freedom and the search for truth"

Outside the text
It is unusual to quote an idea and only mention the author in brackets. Here, the writer has probably mentioned Henderson previously, before quoting him. It is important in most disciplines to cite the exact page number when you quote. E.g.:
"Universities are the guardians of intellectual freedom and the search for truth" (Henderson, 1969: 25).

See 3.3: Summary and Paraphrase for more important differences.

In combination
You may want to fit the key part of a quotation into your text. It is best to begin verbatim (i.e. word-for-word) quotation at the beginning of a phrase, & not in the middle; e.g.:
In those days, universities were regarded as "the guardians of intellectual freedom and the search for truth" (Henderson, 1969: 25).

Notes: It would have been inappropriate to begin the above quote in the middle of the underlined phrase.
