defined simply as the inverse of differentiation. Even Lacroix wrote that “the integral calculus is the inverse of the differential calculus, its object being to ascend from the differential coefficients to the function from which they are derived.” Although Leibniz had developed his notation to remind one of the integral as an infinite sum of infinitesimal areas, the problems inherent in the use of infinities convinced eighteenth-century mathematicians to take the notion of the indefinite integral, or antiderivative, as their basic notion for the theory of integration. They of course recognized that one could evaluate areas not only by use of antiderivatives but also by various approximation techniques. But it was Cauchy who first took these techniques as fundamental and proceeded to construct a theory of definite integrals upon them.

point, but there is evidence that Cauchy was reproached by the directors of the school. He was told that, because the École Polytechnique was basically an engineering school, he should use class time to teach applications of differential equations rather than to deal with questions of rigor. Cauchy was forced to conform and announced that he would no longer give completely rigorous demonstrations. He evidently then felt that he could not publish his lectures on the material, because they did not reflect his own conception of how the subject should be handled.

definition. Cauchy also proved general existence theorems in the theory of differential equations. Instead of asking how to integrate a special function or a special differential equation (that is, finding an analytic expression for the solution), Cauchy began the process of establishing the existence of the integral for a wide class of functions (or differential equations). He thus started an important process towards a qualitative mathematics which was carried further by Sturm-Liouville theory and by Poincare (see Chapter 11).
456: 446: 425: 392: 1213:. Moreover, having a rigorous formalization of integrals requires not only a formal definition of limits, but also the proof that the limit does not depend on the way of dividing the interval of integration. So, my interpretation of Katz's quotation is that "Cauchy was the first to define integrals from limits", but this does not imply that it is not Riemann who "first formalized rigorously integrals, using limits". So, unless better sources are provided, section 302: 266: 588: 538: 236: 383: 2124:, Cauchy presented the details of a rigorous definition of the integral using sums. Cauchy probably took his definition from the work on approximations of definite integrals by Euler and by Lacroix. But rather than consider this method a way of approximating an area, presumably understood intuitively to exist, Cauchy made the approximation into a definition. 1026: 2182:.… Riemann now asked a question that Cauchy had not: In what cases is a function integrable and in what cases not? Cauchy himself had only shown that a certain class of functions was integrable, but had not tried to find all such functions. Riemann, on the other hand, formulated a necessary and sufficient condition for a finite function 2866:
There is a curious story connected with Cauchy’s treatment of differential equations. Cauchy never published an account of this second-year course, and it is only recently that proof sheets for the first thirteen lectures of the course have come to light. It is not clear why these notes stop at this
2376:
On the other hand, I disagree with formulations such as "the first to have formalized...": In this context, the concept of formalization as well as the concept of rigor has evolved over the time (let us recal that the first formal definition of the real numbers dates from the second half of the 19th
1688:
To me, it is clear that Cauchy is the first to rigorously define integrals in the modern sense, unless somebody else did before him. He did it at the latest in 1823, thirty years before Riemann On the other hand, Cauchy seemed mainly interested in actually integrating functions, rather than studying
1742:
What I'm taking out of this is that we can probably say that Riemann can be credited with turning integrable functions into an object of study, and this is likely why so many people say that he's the first to rigorously define the integral. Incidentally, since Riemann's and Cauchy's definitions of

Cauchy broke radically from his predecessors with his definition of the integral… Leibniz had considered integrals as sums of infinitesimals but from the Bernoullis onwards it had been customary to define integration as the inverse process of differentiation. This made the indefinite integral the

Euler and his contemporaries had already used left sums to approximate integrals, and Lacroix and Poisson had tried to prove that they converge to the integral in a suitable sense. One can find many elements of Cauchy's arguments in these papers as well as in Lagrange's proof of the fundamental
2008:
In spite of the appeal of Lagrange’s method in England, Cauchy, back in France, found that this method was lacking in “rigor.” Cauchy in fact was not satisfied with what he believed were unfounded manipulations of algebraic expressions, especially infinitely long ones. Equations involving these
1999:
In his calculus texts, Cauchy defined the integral as a limit of a sum rather than as an antiderivative, as had been common in the eighteenth century. His extension of this notion of the integral to the domain of complex numbers led him to begin the development of complex analysis by the 1820s.

Cauchy’s treatment of the derivative, although using his new definition of limits, was closely related to the treatments in the works of Euler and Lagrange. Cauchy’s treatment of the integral, on the other hand, broke entirely new ground. Recall that, in the eighteenth century, integration was

1102:
Even though what it means to “rigorously formalize” something is somewhat subjective, I would argue that Cauchy “rigorously formalized” integration (of piecewise continuous functions) some decades before Riemann. Indeed, the same reference (Katz 2009, pp. 776–777) seems to say the same thing:

In the case of the integral the earlier approximation techniques led Cauchy to a definition which allowed him to prove the existence of the integral for a specific type of functions. No one seems to have asked this existence question before, nor could it have been answered with the earlier

For such functions, he shows (implicitly using the fact that a continuous function 2487:
Cauchy followed Fourier when he focused on the definite integral, but instead of relying on a vague notion of area, Cauchy defined the definite integral as the limit of a "left sum". This was much more precise and it allowed him to prove that the integral exists for a continuous

As Euler knew the concept of limits, it seems unbelievable that he did not know a definition of integrals in terms of limits. So, it seems difficult to decide who was the first to use limits for defining integration, and what is exactly the contribution of

It seems pretty clear to me that Katz views Cauchy as having first rigorously formalized the integral, as part of a larger program of introducing rigor in analysis in general, and Riemann having expanded on Cauchy's work.

In 1853, Georg Bernhard Riemann (1826–1866) attempted to generalize Dirichlet’s result by first determining precisely which functions were integrable according to Cauchy’s definition of the integral
2005:
Section 22.1 is “Rigor in Analysis”, and subsections 22.1.1-5 (“Limits“, “Continuity”, “Convergence”, “Derivatives”, and “Integrals”) are essentially all about Cauchy's work. The section opens with:

engineers. So, the fact that many antiderivatives of common functions cannot be written in closed form was certainly a strong motivation for emphasizing on integrals rather than on antiderivatives.

I think what any of us finds believable or not should have less importance than what solid secondary sources are saying on the question. Katz is extremely clear that Cauchy is the first to have

Rubi, a computer algebra system rule-based integrator, pattern matches an extensive system of symbolic integration rules to integrate a wide variety of integrands.

In particular, it was Cauchy, not Riemann, who first used limits to define the integral of a function. Is there any reason not to change the text to reflect this?

So I think that you're asking why the article presents Riemann integrals instead of Darboux integrals. That's a fair question. I don't know the answer.
2951: 2916: 1173:
Thanks for raising this issue. It would help to have a clearer statement of the timeline, because Cauchy and Riemann overlapped in time. According to
2863:, Cauchy was scolded by Polytechnique for focusing too much on rigor and not on practical, engineering-oriented stuff. Quoting Katz again (p. 779): 1188:
Once we establish the basic facts, then it would be good to understand why so many authors seem to attribute the first rigorous integral to Riemann.
