'''Mark Edward Mahowald''' (December 1, 1931 – July 20, 2013) was an [[United States|American]] [[mathematician]] known for work in [[algebraic topology]].<ref>{{cite web|url=http://www.legacy.com/obituaries/chicagotribune/obituary.aspx?n=mark-edward-mahowald&pid=165996488&fhid=2074#fbLoggedOut |title=MARK EDWARD MAHOWALD Obituary: View MARK MAHOWALD's Obituary by Chicago Tribune |publisher=Legacy.com |date=2013-07-20 |accessdate=2013-07-24}}</ref>
 
==Life==
Mahowald was born in Albany, Minnesota in 1931.<ref>http://books.google.ca/books?id=allYAAAAMAAJ&q=%22Mahowald,+Mark+edward%22+1931&dq=%22Mahowald,+Mark+edward%22+1931&hl=en&sa=X&ei=ue7xUYzAL6PfiAK5qoGYDg&ved=0CDcQ6AEwAg</ref> He received his Ph.D. from [[University of Minnesota]] in 1955 under the direction of [[Bernard Russell Gelbaum]] with a thesis on ''Measure in Groups''. In the sixties, he became professor at [[Syracuse University]] and around 1963 he went to [[Northwestern University]] in Chicago.
 
==Work==
Much of Mahowald's most important works concerns the [[homotopy groups of spheres]], especially using the [[Adams spectral sequence]] at the prime 2. He is known for constructing one of the first known infinite families of elements in the stable homotopy groups of spheres by showing that the classes <math>h_1h_j</math> survive the Adams spectral sequence for <math>j\geq 3</math>. In addition, he made extensive computations of the structure of the Adams spectral sequence and the 2-primary stable homotopy groups of spheres up to dimension 64 together with Barratt, Tangora and Kochman. Using these computations, he could show that a manifold of [[Kervaire invariant]] 1 exists in dimension 62.
 
In addition, he contributed to the chromatic picture of the homotopy groups of spheres: His earlier work contains much on the image of the [[J-homomorphism]] and recent work together with Goerss, Henn, Karamanov and Rezk does computations in stable homotopy localized at the [[Morava K-theory]] K(2).
 
Besides the work on the homotopy groups of spheres and related spaces, he did important work on [[Thom spectrum|Thom spectra]]. This work was used heavily in the proof of the [[nilpotence theorem]] by Devinatz, [[Michael J. Hopkins|Hopkins]] and Smith.
 
==Awards and honors==
In 2012 he became a fellow of the [[American Mathematical Society]].<ref>[http://www.ams.org/profession/fellows-list List of Fellows of the American Mathematical Society], retrieved 2013-02-02.</ref>
